SLWB 1H - Bronze Plain Bearing

Wrapped Bronze With Lubrication Holes - low-maintenance

SLWB 1H - Bronze Plain Bearing

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.
