PTFE sliding bearings

PTFE Composite dry sliding bearings are suitable for applications where
the load and self-lubrication requirements are high.

Self lubricating bushings with PTFE sliding layer

Description

PTFE sliding bearings metric size made to order from china

Material PTFE Composite dry sliding bearings made of material strength of steel with the low friction of a PTFE-based self-lubricating sliding layer. The intermediate layer of porous tin bronze guarantees a strong bond between the backing and sliding surface and also improves the dissipation of heat generated during operation. The bearing is available in bronze backed,stainless steel backed. sliding layer without any lead also in available. To protect the bearings from corrosion the steel backing is tin-plated. PTFE Composite dry sliding bearings can be machined, except for the sliding surface. however, a calibration is possible within certain limits.
