Material - Characteristics

 

Sliding elements made of solid tin bronze (CuSn8) with lubrication holes, which serves as a lubricant reservoir.

 

Larger amounts of the lubricant can be stored due to the hole depots, resulting in longer maintenance intervals.

 

These plain bearings are only suitable for grease lubrication.
