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.
