SLPI B - Bronze Plain Bearing
Solid Bronze Plain Bearings - high-maintenance
Material - Characteristics
Standard plain bearings made from solid tin bronze, aluminum bronze or brass. These bearings will be produced according to DIN ISO 4379 (formerly DIN 1850-1) as well as customer drawings.
Available with and without lubrication grooves. Suitable for grease and oil lubrication.
