deva.bm® sliding bearings Maintenance-free, self-lubricating

deva.bm

®

Self-lubricating composite bearing material Contemporary designs represent an enormous challenge to modern-day bearing materials because, frequently, zero maintenance maintenance is expected under severe to ex treme conditions as well as under maximum loads. The constant pressure on costs additionally calls for increasing uptime of machinery and equipment and uncompromising standards of operational reliability. The maintenance-free, permanently self-lubricating heavy-duty bearing materials materials from the DEVA® product range offer bearing solutions guaranteed to operate reliably and safely over a long term.

1 Materiall properties Materia proper ties deva.bm® is a self-lubricating composite bearing material, comprising a steel backing with a sliding layer of deva.metal®. deva.bm deva.bm is  is produced using a special sintering process to get the following advantages:

deva.bm         



normally requires no lubrication. allows maintenance-free operation. possesses a high static and dynamic load-bearing capacity. has a low coefficient of friction. is stick-slip-free. offers a high margin of safety against mating material damage. is utilisable in dusty environments. is utilisable at temperatures ranging from -190 °C to +280 °C. is utilisable in corrosive environments.

     

does not absorb water and guarantees maximum dimensional accuracy. is utilisable in seawater. is utilisable in radioactive environmen environments. ts. is electrically conductive. No electrostatic charging effects occur. is suitable for rotational, oscillating and linear movements. is suitable for micro movements. is suitable even for applications involving involving high edge pressures.

2 Materiall structure Materia s tructure Solid lubricants used It is additionally possible to apply an initial surface film to support running-in phases in which the r unning conditions are purely dry. The thickness of the runningin-film is not considered in any bushings bore tolerance because it will be consumed during the running-inperiod. Where used with conventional lubricants, the graphitecontaining deva.bm deva.bm sliding  sliding layer can be impregnated with oil.

Layer structure and microstructure of deva.bm The distinguishing features of deva.bm deva.bm are  are its highly durable steel backing and the bronze matrix with homogeneous solid lubricant indentations that ensure low friction coefficients. The latter is either graphite of varying particle form and size, or PTFE.

1)

Under optimum operating conditions.

2)

The stated sliding friction coefficients are not guaranteed properties. They have been determined on our test rigs using field-proven parameters that do not necessarily reflect the actual application of our products and their service environment. We offer customer-specific friction and wear tests on request.

3)

 Axial bearings tend to higher friction coefficients than radial bearings. –U = 1.5 if dimples and grease lubrication are used p

4) 5)

 In case of higher loads (>50 MPa) superposed by an (expected) high number of sliding cycles, the use of deva.bm 309 (same alloy+lubrication dimples) with an additional lubrica nt is recommended.

4 Mating material The deva.bm® bearing materials can be used only with mating materials demonstrating a hardness of at least 180 HB. Where lubricant is additionally addition ally introduced into the sliding contact, hardness values of >130HB are also permissible. In abrasive environments, a surface hardened to 35 HRC/45 HRC should be used. The ideal mating surface roughness for deva.bm deva.bm is  is Ra = 0.2 to 0.8 µm, produced by grinding. Rougher surfaces are also acceptable, depending on the operating conditions. To obtain the r ight surface roughness, it is equally possible to use bushings of a suitable hardness. Hardfaced or galvanized protective layers (normally coated, hard-chrome, nickel-plated) can also be used to a limited extent.

Both substances are classified as hazardous. We expressly draw attention to dealing with hazardous substances. Safety data sheets are available on request. To achieve a uniform supercooling, the dry ice should be crushed to about the size of a walnut. The sliding bearings should be completely immersed when using liquid nitrogen. The time required for complete supercooling of the bearings is between 15 minutes t o 1 hour depending on the volumes of the parts to be cooled.

deva.bm sliding plates – Hole spacing and ins tallation Notes The number and size of the screws depends on the occurring stresses and the shearing forces to be withstood as a result. We recommend as guide values: b1 = 10 - 30 mm – mm  – if b 1 < 4 mm, should nicks be made as shown in the drawing below, in order to avoid chipped sliding layer edges. l1 = 60 - 150 mm b ≈ (1 - 1.5) D
