Description

The performance of POM Composite bearings depends on the interaction of load, lubrication, surface roughness, sliding velocity, and temperature encountered in specific applications.

POM Composite – plain cylindrical bushings:3 layers : a steel or bronze strip to improve mechanical resistance – a porous sintered bronze layer for heat conductivity, dimensional stability and the bonding of the sliding layer – a PTFE based sliding layer with good auto lubrifiant quality (low wear and low friction).

Application recommendations:

Shaft tolerance h7 – h8

Housing tolerance H7

Shaft roughness Ra, µm 0 .. 0,8

Shaft hardness, HB 150 – 600
