Bushing

Composite plain bearings are primarily used for bearing arrangements where heavy loads have to be supported and where rotational or oscillating movements are relatively slow. Because of their good sliding properties and compact design, these plain bearings are particularly
suitable for bearing arrangements where

• maintenance-free operation is a prerequisite
• there is a risk of lubricant starvation
• lubricants can not be used or are forbidden
• space is limited.

There are two standard types of composite
material for SKF plain bearings: PTFE composite
and POM composite. Each is suitable
for different applications.
PTFE composite
PTFE composite bearings consist of a copperplated sheet steel backing on which a 0,2 to 0,4 mm thick porous layer of tin/bronze is sintered († fig. 1). By a rolling process, the pores of the sintered layer are filled with a mixture of PTFE (polytetrafluoroethylene) and
• lead, designation suffix B, or
• molybdenum disulphide, designation suffix E.
An additional 5 to 30 μm thick running-in layer of the mixture is then applied to the sintered tin/bronze. This additional layer provides an  optimum combination of the mechanical properties of the sintered tin/bronze and the good sliding and lubricating properties of the PTFE mixture. PTFE composite bearings have good dimensional stability and thermal conductivity.

PCM .. B : Metric plain bushings of triple-layer PTFE composite material, with lead additives 28. Suitable for bearing arrangements that have to support radial loads only.
For slow rotational or oscillating movements. Initial lubrication not required.

Maintenance-free.
