- SLWB 1H
wrapped BRONZE PLAIN BEARINGS
wrapped bronze with hole depots – low maintenance
MATERIAL CHARACTERISTICS
Sliding elements made of solid tin bronze (CuSn8) with hole depots serving as a lubricant reservoir.
The hole depots allow larger quantities of lubricant to be stored, resulting in extended maintenance intervals.
These plain bearings are suitable for grease lubrication only.
