Product Description

P20 Self-lubricating bearing

 

The P20 bearings will be distributed by the orifice according to process characteristics according to ISO 3547 with a sliding wall in advance on the surface in contact with the parts. This design is well suited for ground maintenance of grease or liquid lubrication applications.

 

 

P20 Material properties

1. Low adhesion with parts during movement

Low friction and high wear resistance

3. The material has certain clearance and deformation, which can absorb the impurities produced by the movement and thus improve the life.

4 Corrosion resistance can be based on the actual use of galvanized and other solutions.

The stainless steel matrix has good chemical resistance
