SLWB 1H - Bronze Plain Bearing
Wrapped Bronze With Lubrication Holes - low-maintenance
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.
