Material information
  • Low-maintenance standard solutions
Plain bearing production
Sliding elements in a great variety of designs are produced from the composite material in cutting, stamping and shaping processes.

Standard designs are:

  • Cylindrical bushes
  • Thrust washers
  • Strips
Characteristics
Material composition
Strips
Bushes
Thrust washers

Standard version: Tin
layer thickness: approx. 0.002 mm

If these material sections are used to create slide paths, they have the following main functions:

  • Absorbing and transferring forces acting vertically to the running surface
  • Fixing moving components to each other
  • Ensuring guidance accuracy for axial movements over the entire service life

 

Strips are available in two material groups:

  • Material group P1 for maintenance-free, dry-running applications
  • Material group P2 for low-maintenance, lubricated applications


For the advantages of each group and help deciding which material group is best for the relevant use, please refer to the information provided in the section cylindrical bushes, flange liners and thrust washers.



VSB-20 Flange liners PAF
· marginally lubricated bushings for grease or oil lubricated applications
· Standard parts contain grease indents in the sliding layer; plain sliding layer available by request
· Optimum performance under relatively high loads and low speeds
· Suitable for linear, oscillating and rotating movements
· Wide range of parts available from stock
 
Suitable for rotating and oscillating movement, less maintenance requirements due to the long re-lubrication intervals, lower wear, lower susceptibility to edge loading, no absorption of water and therefore no swelling, good damping behaviours, good resistance to shock loads.


STRUSTURE

1. POM thickness 0.30~0.50 mm. It provides high wearresistance and low friction even with only minute volume oflubricant are supplied, this bearing surface carries a pattern of circular indents which should be filled with grease on assembly of the bearing.
2. Sintered bronze powder thickness 0.20-0.35mm. A special composition of powdered copper is thermally fused to the steel backing. This contact layer acts as an anchor for the PTFE layer and conducts the thermal build up away from the bearing surfaces.
3. Low-carbon steel.Setting the foundation of the bushings, the steel back provides exceptional stability,load carrying and heat dissipation characteristics.

TYPICAL APPLICATIONS


 

 
 
Recommended for applications involving intermittent operation or boundary lubrication... Automotive: suspension joints, kingpin assemblies and stub axles of trucks, automobile driving joint hinges, steering and other linkages, articulation joints, rear chassis hinges, fair leader rollers... Machine tool building industry: spindles in drill, grinding, and milling machines, ram guide plates in multi-ram presses... Agricultural equipment: gearbox, clutch, bale trips and wheel caster swivels for bale accumulators, front axle pivot bearings, steering idler box bearings and kingpin bearings for harvesters... It is especially well-suited for applications where lubricant can not be supplied continuously or repeatedly.
