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

shaft
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
