Symbol bookproduct overview

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.
