Product Description

Pom Bearing Manufacturers & Suppliers - Self-lubricating Bearings

Oil-free self-lubricating bearings give you good partners for cost savings

 

The product is made of high quality low carbon steel with a sintered spherical bronze layer in the middle and a surface rolled modified polyformaldehyde (POM).Under the condition of boundary lubrication, it can be used for a long time without oiling, and there are oil pits on the surface of the wear-resistant layer.

The products are widely used in gold processing machinery, mining machinery, water conservancy machinery, automobile, construction machinery, agricultural machinery, steel rolling industry and so on.

 

Pom Composite dry sliding bearings

We choose low carbon steel as the base of the bearing
