SLPI B - Bronze Plain Bearing

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.

temperature range -40 up to +150 °C
max. PV value 2,8 MPa m/s
max. sliding velocity 2,5 m/s

For Bearing Design

Recommended dimensions:

  • DIN ISO 4379 (replacement for DIN 1850-1)

Recommended fittings for the plain bearing and the sliding counterparts

e7 for standard applications
g7 for high precision
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
