INTRODUCTION Cat Seals Features

Metal Face Seals

• Corrosion-resistant seal rings • Precision machined, self-renewing sealing surfaces • Minimum face load variations • Special seal and load ring materials to match application requirements

For more than 60 years industrial original equipment manufacturers and equipment users have turned to Cat® Seals to protect their components from extreme, abrasive, and corrosive environments. Caterpillar is the leading manufacturer of metal face seals providing the best solutions for tough applications. Cat Seals innovative designs and engineering protect a broad range of equipment and machinery working in adverse conditions such as mud, rock, sand, chemicals, water, heat and cold.

Rotating speed, lubrication, temperature, and differential pressure are factors to consider when determining seal face loads. Cat Seals provide good performance across a wide range of face loads, therefore, compensating for considerable assembly tolerance buildup, misalignment, and wear.

Cat Seals are proven to provide long service life with low maintenance resulting in increased equipment up time, productivity and customer satisfaction.

Long Life Extensive laboratory and eld testing has conrmed Cat Seals last much longer than other radial lip seals. Used for decades by manufacturers of heavy construction equipment, Cat Seals have reached over 30,000 hours of operation without maintenance, in some applications. As wear occurs, machined metal seal faces are automatically and continually renewed.

Caterpillar offers Cat Duo-Cone and Heavy Duty Dual Face seals. Both designs use various elastomeric load rings and various seal ring material. Cat Duo-Cone seals require less space radially and Heavy Duty Dual Face seals require less space axially in a housing. Cat Duo-Cone seals incorporate a round toric while Cat Heavy Duty Dual Face seals have a trapezoidal Belleville Washer.

Problem Solver

Protecting Products

The high cost of equipment downtime requires the best quality seal available. The Cat seal provides superior performance in extreme applications where lubricant retention and the ability to keep out damaging and/or abrasive materials are essential. Construction, mining, industrial, forestry, petrochemical, paper, agriculture, sewage treatment, landll, and many more applications are all examples where Cat Seals have improved bearing protection and overall performance.

Cat Seals provide protection for internal working components like bearings and gears in abrasive applications and permit the use of oil as a lubricant instead of grease resulting in less friction and longer life. In most applications, the lubricant installed at the factory is permanent with no periodic lubrication or adjustment required. Unscheduled equipment down time is very costly. Cat Seals provide superior performance in extreme applications where lubricant retention and protection from damaging surroundings is essential. Years of proven eld experience has shown Cat Seals provide long life in many applications. Manufacturers in a variety of industries have utilized Cat Seals in their equipment for decades.

Application Engineering Caterpillar Engineers are available to understand and analyze your sealing requirements, work with your engineering department, and recommend the Cat seal that will best meet your needs. You need only complete an application data sheet (found at www. cat.com/cat-seals) and provide drawings of the area containing the seal.

Design The design of a Cat seal compensates for many manufacturing and operating variables. Two metal sealing rings oat in position; two elastomeric torics or Belleville washers exert uniform pressure to accurately position the metal rings and serve as the static seal between the housing and the seal ring. The load rings also transmits the turning torque from the drive housing to the seal ring.

C6 C6 was developed for applications that require high speed and superior corrosion resistance. This alloy offers greater speed capabilities over Stellite with higher resistance to scoring, wear, and corrosion. The C6 alloy is available only from Caterpillar. It is the material of choice around the world in large diameter wheel applications.

Stellite Stellite has been designed for the harshest operating environments where abrasive and corrosive elements are present. Stellite’s formulation is iron based with a high alloy content designed to provide better corrosion resistance. Stellite cast seals are typically found in applications frequently exposed to abrasive and corrosive conditions with moderate rotational speeds. Typical applications include crawler tractor nal drives and various undercarriage applications.

NiHard NiHard is another iron based casting alloy offered by Caterpillar. Pressure velocity characteristics are slightly greater than Stellite, but wear life and corrosion resistance have shown to be less, in tests conducted by Caterpillar. Typical applications would include undercarriage and nal drive applications where corrosion resistance is not essential, but seal surface speeds prohibit the use of Stellite.

Formed (Cat Duo-Cone only) Formed seals were developed for applications that do not require the high levels of corrosion and abrasion resistance, but the versatility of a face seal is desired. Formed seals are used extensively in axle, winch, and nal drive applications. Formed seals are interchangeable with cast seal retainers, provide similar load and speed capability as the Stellite seals, at a signicantly lower cost.

Forged Forged seals are available on a limited basis from Caterpillar. These seals have been used successfully on undercarriage applications where minor wear is present and seal cost is critical.

Nitrile (NBR) Nitrile is compatible with most mineral-based lubricant oils. Nitrile load rings offer the maximum resistance to abrasion. It is the most common load ring material choice and is used in most standard axle, nal drive, and undercarriage applications.

Low-Temperature Nitrile (LT-NBR) Low-temperature Nitrile was specically developed for highly abrasive, low-temperature applications. Typical applications include undercarriage idlers, rollers and nal drives.

Silicone Silicone uses are extreme high (wet disc brake systems) or extreme low (arctic environment) temperature applications.

Hydrogenated Nitrile (HNBR) Hydrogenated Nitrile is a Nitrile-based material and has very similar abrasion resistance characteristics to standard Nitrile, but Hydrogenated Nitrile has better temperature resistance to permanent deformation.

Fluoroelastomer (FKM) FKM is a uoroelastomer and is typically used where extremely high temperatures are a concern and low temperatures are never a problem.

PRODUCT DESIGN REVIEW Seal Group Size (Class) Options Seals are available in various radial cross sections with toric sections from 4.30 to 16.00 mm (0.170” to 0.630”). Always specify the largest toric/seal group section that can be accommodated in the housing design envelope. Larger section torics will accommodate greater deection and are less sensitive to tolerances and environmental effects. The table shown below gives a brief summary of available design options.

Class A - 4.30mm (0.17”) Cat Duo-Cone seals utilizing the 4.30 mm cross-section toric ring have very limited applications. They are used in small diameter applications with extreme axial and radial spacial and tolerance constraints (e.g. cartridge pins). Seals of this type have very little end play capability.

Class B - 6.22mm (0.24”) Cat Duo-Cone seals with 6.22 mm cross section toric rings are typically used in small axle or rock bit applications. They are used where sealing is needed in extreme environments, but where there is insufcient space to put a larger (and more typical) cross section Cat Duo-Cone seal. While these seals do have some end play capability, they have less than seals utilizing larger cross section load rings.

Class C - 9.47mm (0.37”) 9.47 mm cross-section Cat Duo-Cone seals are typically used in moving undercarriages for crawler tractor and excavator applications. These seals have good end play capability. Seals are available with 8 o, 15o, and 20 o seal ramps to serve different operating environments.

Class D - 12.70mm (0.50”) This style Cat Duo-Cone seal is very common in axle, wheel, and nal drive applications in construction and earth moving equipment. These seals have very good end play capability. Seals are available with both 8 o, 15o, and 20o seal ramps for optimized performance in your application.

Class L - 16.00mm (0.63”) Currently, the largest cross section toric ring offered by Caterpillar, the 16.0 mm cross section diameter Cat Duo-Cone seal is for the largest of sealing applications.

Class E - Inverted Cat Duo-Cone Seals Inverted Cat Duo-Cone Seals specialized design for spacial restraints, used for large shaft clearance.

Class K - Cat Heavy Duty Dual Faced Seals The Cat Heavy Duty Dual Faced Seal uses a square bore housing design and a Belleville Washer load ring to provide loads to the metal seal faces. This seal is designed for demanding environments and is available in many sizes. Because of the design, there is no rolling of the loading member. This seal type is used in a wide variety of products, including undercarriage, axles, nal drives, gear boxes, wheels, etc. Contact Caterpillar with your seal class questions at [email protected]

PRODUCT DESIGN REVIEW Cat Duo-Cone Seal Ramp Angles  A unique feature of Cat Duo-Cone seals is the changing of sealing ramp angles to tailor the seal to various operating environments. Below is a brief summary of the purpose of various ramp angles.

8o Seal Ramp Cat Duo-Cone seals with 8 o seal ramps were originally developed for applications that are exposed to highpressure differentials. This design offers increased toric retention and a more linear face load prole over its range of operation. The 8 o Cat Duo-Cone seal is available in both cast alloy and formed steel designs. Formed Cat Duo-Cone seals are interchangeable with cast Cat Duo-Cone seal retainers.

15o Seal Ramp The 15o Cat Duo-Cone seal is the most common design offered by Caterpillar. This sealing design offers resistance to internal operating pressure and is most commonly used in nal drive, axle, and wheel applications.

20o Seal Ramp Similar to the 15 o seal design in that it resists internal pressures. The 20 o design produces less compression on the toric and because of its bore requirements being shallow, requiring less room axially in its application, the 20o seal ramp is commonly found in undercarriage applications.

DESIGN INFORMATION Load Defection The combination of the seal ring ange thickness and gage diameter or Heavy Duty Dual Faced Seals inner diameter and elastomeric materials dictate the allowable operating conditions the seal can be used in. The sealing system, the nominal Duo-Cone gap between housings or HDDF operating range and axial tolerance stack will ensure the seal will perform. The Cat seal options are based on those operating conditions. Caterpillar Engineering should be consulted at [email protected] for proper seal selection and design.

New

Partially Worn

Formed seals are more exible than cast seals and as a result will produce a different wear pattern than cast rings. Typically, formed seals wear in an axial rather than radial direction, as depicted below, due to their increased exibility. Development of a Wear Lip in these two areas makes it necessary to install a new seal.

Speed Capability The face load required to keep the metal seal rings in contact is related to the targeted speed of the application. Many factors inuence this relationship, including seal ring material, seal ring diameter, operating temperature, lubricant viscosity, differential pressure across the load rings and action of centrifugal force on the load ring.

Location of Wear Lip

Lubricant Requirements Cat Seals are a mechanical face sealing technology that require lubrication. Oil lubricant should be used with all Cat Seals. Mineral base oils ranging from 10WT to 90WT are commonly used, depending on temperature requirements. Extreme pressure gear lubricants should be used with caution, as some additive packages are not compatible with polymers.

In low speed applications or with light lubricants, face pressures are generally increased to ensure seal ability. The same is true when seals are exposed to high differential pressures and/or large end play or deections. Lower face loads are specied for applications producing high rotational speeds or high ambient outside temperatures.

In some slow rotating or oscillating applications, certain types of grease may be used, but mineral base oils are always preferred.

High speeds produce high temperatures which deteriorates lubricant and changes the properties of the elastomer load rings. Depending on the cavity design, high speeds can centrifuge lubricant away from the seal face. All conditions can contribute to adverse sealing effects. Consult Caterpillar at [email protected] when selecting face load to ensure appropriate design target for your desired speed.

Contact Caterpillar for additional information at [email protected] Oil not only provides lubrication to the sealing faces, but also serves to cool the seal rings. Lubricants are recommended to cover a minimum of one third of the sealing surface, depending on the diameter of the seal, to properly lubricate and cool the rings. Cat Seals work best in clean, closed systems. To allow adequate volume for thermal expansion, nonvented cavities should not be lled more than 90% full. Maximum care should be taken to ensure lube cavities are clean at assembly – free from dirt, scale and other foreign materials.

Seal Wear Measurement Cast Cat Seals automatically compensate for wear. The mating faces form a contact band approximately 0.5 (0.02“) to 1.0 mm (0.04”) wide that retains the oil lubricant and seals out all foreign material. As wear occurs, the contact band will widen slightly and migrate inward until the inside diameter is reached.  As depicted in the gure below, the cast seals wear down the tapered surface.

Testing Caterpillar laboratories are equipped with the latest technologies and testing procedures for development and validation of new seal designs. Contact Caterpillar for testing options at [email protected]

* Commercially available CD/TD-2 oils that meets requirements ** EP gear lubricants should not be used with seals having silicone torics. Consult with Caterpillar before specifying an API GL-5 or MIL-L-2105C type lubricant.

Reliability Testing Reliability testing is used for evaluating the operating conditions of the specic seal application including the following: seal face loads, internal operating temperatures, internal operating pressures, rotational speeds, etc. and evaluate the performance of the seal to determine a metal seal ring material’s resistance to failure. This test method also determines the maximum speed at which the seal group can perform.

NOTE: Arctic Lubricants – For operation with ambient temperatures below  –20oC (-4oF), use oils with base stocks that have low temperature ow capabilities. Use oils with a CD/TO-2 rating. If the application requires  API GL-5 gear oil, use the EP synthetic gear lubricants that are available. Low temperature lubricants are not recommended for temperatures above 0oC (+32oF). When operating temperatures reach 0 oC, the oil should be changed to one of the lubricants indicated above.

Specialty Seals Caterpillar not only offers “off-the-shelf” designs – our team is also available to work with your engineers to design customized or application specic Cat Seals. Whether developing a new seal size or type to t your application, or integrating a new metal seal or load ring material, Caterpillar Engineers have the experience necessary to design, procure and test these concepts then produce them.

Product Comparison In most applications, either Cat Duo-Cone or Heavy Duty Dual Face seals can be utilized. However, there are specic advantages to both designs. These should be considered when designing a Cat seal into your application:

Load Testing Load tests evaluate the loading characteristics of the elastomeric ring for a given size. This information is used to determine the load ring compression required to obtain optimal loading on the metal seal faces.

Accelerated Wear Tests  Accelerated wear testing employs equipment to evaluate a seal ring material’s resistance to abrasive wear. Seals are assembled and submerged in a unique slurry to accelerate the wear process. Wear is quantied by the amount of movement of the sealing band during the test.

Oil Compatibility Testing Oil compatibility testing evaluates the effects f rom exposure with the intended system lubricant and compression level of the system design. This procedure will indicate the rate at which the elastomer will relax during operation and cause a change in load at the seal group interface. The test guides Caterpillar Engineers to identifying the correct load to design for maximum seal life.

Cat Duo-Cone Seal • Requires less room radially in application • Very stable in housing prior to nal assembly • Very good end play capability

Cat Heavy Duty Dual Face Seal • Requires less room axially in application • Square bore housing cavity design • No assembly tool or lubricant required

DESIGN INFORMATION Mud Packing

 A properly installed Cat seal creates a robust system performing without premature failure. The following considerations should be addressed when designing your system.

Mud packing is a common issue in environments where the Cat Seals are continually exposed to dirt and mud. Debris can pack the cavity between the seal housing, seal ring and load ring. Over time, this can cause the load ring to be pushed out of position.

Uneven or Excessive Face Load The seal ring is tilted in the retainer or the toric is twisted result in improper seal installation and can cause uneven loads at the seal interface. This uneven loading can result in premature failure.

Seal guarding and labyrinths can prolong seal life if applied correctly. Poor labyrinth application can trap debris against the seal and lead to wearing away of the seal housings.

Mishandling of Seals Mishandling of seals can lead to an immediate leak or premature failure. Failure can occur due to cutting or tearing of the elastomeric load ring, breakage of the sealing ring, contamination of the seal face with dirt or lint, etc. When assembling Cat Seals, please carefully observe assembly instructions provided by Caterpillar.

Internal Pressure Spikes Cat Seals can withstand a varying amount of system pressure, depending on the design. If your application requirements include pressure capability, consult Caterpillar Engineering at [email protected]

If your application requirements include resistance to excessive debris, contact Caterpillar at [email protected]

Load Ring Abrasion  Abrasion of the load ring can occur in applications where it is exposed to abrasive conditions like corrosive, dusty, dirty, sandy, and rocky. Abrasion of the load ring causes deterioration and tearing of the elastomer, leading to failure. This can be minimized through proper load ring material selection. Consult Caterpillar to discuss your seal load ring options at [email protected]

Improper Housing Design It is critical that the application seal housing conform to the design information provided by Caterpillar. The relationship between the seal assembly and its mating component is essential to the performance of the sealing system.

The Proper Selection of Oil Improper selection of oil can have an adverse effect on both the load ring and metal sealing ring. Some oils are incompatible with elastomers and cause long-term degradation with exposure, especially when combined with heat. Improper oil selection can cause metal seal failure due to galling from inadequate lubrication ow.

Housing Preparation

• (2) Metal Seal Rings • (2) Elastomeric Toric Rings

The housing components that contact the rubber  toric rings (3 and 4) must be free from foreign material (oil, grease, dirt, metal chips, dust or lint particles, etc.) before installing the seal. This should be done using a lint-free wipe and a non-petroleum based solvent. Dry with a clean wipe.

Terminology

Remove any foreign material from the rubber torics (2), the ramps (7) and the lips (8) of both seal rings. This should also be done with a lint-free wipe and a non-petroleum based solvent. Dry with a clean wipe.

1. Seal Ring 2. Rubber Toric 3. Housing Retainer Lip 4. Housing Ramp 5. Seal Ring Housing

Place the rubber torics on the metal seal ring at the bottom of the seal ring ramp and against the retaining lip.

6. Seal Ring Face 7. Seal Ring Ramp 8. Seal Ring Retaining Lip 9. Installation Tool

Handling the Seals The idea is to protect the seal face. The more precausions taken, the more likely the seals will last in the eld.

Make sure the rubber toric is straight on the seal ring and not twisted. Be careful not to nick or cut the torics during the assembly, as this can cause leaks.

Staging When staging, have the seal package on the top shelf of the kit cart or on a atbed kit cart. (Reasoning: the seals need to be removed from the packaging from the center aps)

Put the installation tool onto the metal seal ring and rubber toric. Lightly dampen the lower half of the rubber toric with the appropriate assembly lubricant. Techniques to dampen the toric include wiping with a lint-free towel, lubricating using a clean foam brush, or dipping in a container lined with towels saturated in the assembly lubricant (as shown).

Stacking Make sure seal packages are not stacked more than 5 high to reduce the risk of tipping during transit. (No banding or wracked straps should be used)

Package Removal Do not remove the seal from the secondary packaging when transporting the seal. This will help ensure the seal does not get damaged and protects it from contamination. Remove seal from the center aps of the packaging, allowing more access to the seal and reduce the risk of the seals sliding against each other or another surface causing damage to the seal. Cut the center tape, making sure the knife point is not going to cut the toric or seal. (Use of a safety knife is the best tool for this procedure)

Seal groups with silicone torics can be assembled using a freezer to slightly contract the toric rings. Seal groups should be placed in a freezer for 5 minutes at -40oC to -18oC prior to installation. Contraction will be sufcient to allow installation. Groups should warm to room temperature prior to further assembly.

CAT DUO-CONE SEALS INSTALLATION Approved Assembly Lubricants

The rubber toric can twist if it is not wet all around during installation or if there are burrs or ns on the retaining lip of the housing. Twists, misalignment, and bulges of the toric (as shown) will result in seal failure. If correct installation is not obvious, remove the seal from the housing and repeat process.

• Isopropyl Alcohol* • Houghto-Grind 60 CT • Quaker ® Solvo Clean 68-RAH  (*) All applicable safety and disposal guidelines for ammable liquids must be followed.

The rubber torics must never slip on the ramps of either the seal ring or the housing. To prevent slippage, allow adequate evaporation time for the lubricant before proceeding with further assembly. Once correctly in place, the rubber toric must roll on the ramp only. The following shows incorrect installations resulting in cocked seals.

Note: Do not use Stanosol or any other liquid that leaves an oil lm and/or does not evaporate quickly.

Installation Process With the lower half of the rubber toric still wet, use the installation tool to position the seal ring and the rubber toric squarely against the application housing (as shown). 9 1

For smaller diameter seals, use sudden and even pressure to push the rubber toric under the retaining lip of the housing. For larger diameter seals, which will not press in with sudden and even pressure, it is acceptable to work the toric past the retaining lip by starting one side and tapping the opposite side of the installation tool with a rubber mallet until it is engaged past the retaining lip of the housing.

Wipe the face of each seal ring using a lint-free wipe. No particles of any kind are permissible on the sealing surfaces. (Even a hair can hold the seal faces apart and cause a leak)

Check the assembled height variation (A) in a least four places, 90 o apart, use a caliper, toolmakers’ ruler or any other calibrated measuring device. A

The difference in height around the ring must not be more than 1.0 mm. If small adjustments are necessary, do not push or pull directly on the seal ring. Use the installation tool to push down and your ngers to pull up uniformly on the rubber toric and seal ring.

 Apply a thin lm of oil on the entire seal face of one or both seals using a lint-free applicator. Oil must not contact surfaces other than the sealing face.

CAT DUO-CONE SEALS INSTALLATION Final Assembly While completing the nal assembly of the unit, make sure that both housings are in correct alignment and are concentric. Slowly bring the two housings together. High impact can scratch or break the seal components. 1

If the rubber toric slips at any location, it will twist, causing the seal rings to cock. Any wobbling motion of the seal is an indication of cocked seals and can cause dirt to enter by pumping mud past the torics. The following examples show the effects of a cocked seal group.

CAT HEAVY DUTY DUAL FACED SEALS INSTALLATION Cat Heavy Duty Dual Face Seal Assembly Contents:

Service Kit Contents:

Remove seal from the center aps of the packaging, allowing more access to the seal and reduce the risk of the seals sliding against each other or another surface causing damage to the seal. Cut the center tape, making sure the knife point is not going to cut the toric or seal. (Use of a safety knife is the best tool for this procedure)

1. (1) Seal Group 2. Installation Instruction

Housing Preparation

1. (2) Metal Seal Rings 2. (2) Rubber Belleville Washers

The housing components that contact the Belleville Washers must be free from foreign material (oil, grease, dirt, metal chips, dust or lint particles, etc.) before installing the seal. This should be done using a lint-free wipe and a non-petroleum base solvent. Dry with a clean wipe.

Field Kit Contents: 1. (2) Rubber Belleville Washers 2. Installation Instructions

Terminology Belleville Washers

Seal rings must be handled with care. Machined seal faces must not be damaged or scratched. All parts are to be free of grease, oil, dirt and scale.

Square Bore

Seal Preparation Shaft

Belleville Washers should be installed ush against the inside shoulder of the metal sealing rings.

Metal Sealing Ring

Sealing Surface Flush

Handling the Seals The idea is to protect the seal face. The more precausions taken, the more likely the seals will last in the eld.

Installation Process Install each half seal (Belleville Washer and sealing ring) into the housing by carefully pushing on the seal half until it is fully seated. Check to be sure that the seal is not cocked and that the washer is seated evenly at the bottom of the bore. If the seal is a single barb design, the barbed half goes in the suspended housing to insure no movement of the seal half during the assembly process.

Staging When staging, have the seal package on the top shelf of the kit cart or on a atbed kit cart. (Reasoning: the seals need to be removed from the packaging from the center aps)

Stacking Make sure seal packages are not stacked more than 5 high to reduce the risk of tipping during trans-it. (No banding or wracked straps should be used)

Oil Lightly

Package Removal

Push

Do not remove the seal from the secondary packaging when transporting the seal. This will help ensure the seal does not get damaged and protects it from contamination.

36

CAT HEAVY DUTY DUAL FACED SEALS INSTALLATION  After installing the seal halves into the unit, wipe both metal sealing faces clean with a lint-free wipe. Apply a thin lm of oil to the sealing faces with a lint free applicator. Oil must not contact surfaces other than the sealing faces.

Final Assembly While completing the nal assembly of the unit, make sure that both housings are in correct alignment and are concentric. Observe carefully that the rubber rings do not unseat from the bottom of the housing. Slowly bring the two housings together. (High impact can scratch or break the seal components) To set the seals, hold one-half of the assembly stationary while rotating the other member a minimum of ten complete revolutions. This is very important!
