SLSO 2 - Composite Plain Bearing
Steel-Sintered-Bronze-POM Composite Material low-maintenance
Material - Characteristics
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.
