Material - Charakteristik

 

Steel with porous sintered tin bronze layer, which is coated with POM as sliding layer.

 

The POM sliding layer creates a low-maintenance bearing material, which is well suited for high loads and low sliding velocities.

 

The grease pockets provide a lubricant reservoir in which larger amounts of the lubricant can be stored, resulting in longer maintenance intervals.
