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.

For Bearing Design
- DIN ISO 4379 (replacement for DIN 1850-1)
|bearing inner diameter||E6 (decreases down to H8 after pressed-in)|
|bearing outer diameter||r6|
Thermal expansion has to be taken into account at bearing temperatures above 80 °C.
|surface roughness||Ra = 0,2 μm up to 0,8 μm|
|minimum hardness||bearing material hardness + 100 HB|
|recommended hardness||> 220 HB for materials SL-3 to SL-5
> 300 HB for materials SL-1 and SL-2
