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
Recommended dimensions:
- DIN ISO 4379 (replacement for DIN 1850-1)
Recommended fittings for the plain bearing and the sliding counterparts
shaft |
|
||||
housing | H7 | ||||
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.
Mating Material
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 |
