SLSP 2 - Composite Plain Bearing

Steel-Sintered-Bronze-PTFE Composite Material - maintenance-free

SLSP 2 - Composite Plain Bearing

Material - Characteristics

Steel with porous sintered tin bronze layer, which is coated with PTFE as sliding layer.

The sliding layer made of PTFE enables maintenance-free, self-lubricating operation with low friction.

For Bearing Design

Recommended fittings for the plain bearing and the sliding counterparts

shaft f7
housing H7
bearing according to DIN ISO 3547-1 (formerly DIN 1494)

Thermal expansion has to be taken into account at bearing temperatures above 80 °C.

Mating Material
