SLSM 1002 - Sintered Bronze Plain Bearing

Bronze-Sintered Metal - maintenance-free

SLSM 1002 - Sintered Bronze Plain Bearing

Material - Characteristics

Self-lubricating, maintenance-free, with fine distributed solid lubricant.

Within the sintered powder metal matrix the solid lubricant (99,9 percent highly clean, chemical neutral electrolyte graphite) is enclosed pre-loaded in micro distribution.

Therefore in order to ensure a maintenance-free, self-lubricating performance there is always sufficient lubrication all over the bearing area, including for small angular movement, vibration, etc.

The highly clean lubricant has the advantage that oxygen corrosion in water or humid atmosphere at the bearing shaft and the surrounding parts will not occur.

For Bearing Design

Recommended minimum wall thickness a: (d = Ø bearing hole)

a = √ (d ⋅ 0,5) up to 10 N/mm²
a = √ (d ⋅ 0,6) over 10 to 25 N/mm²
a = √ (d ⋅ 0,8) over 25 N/mm²

Recommended fittings for the plain bearing and the sliding counterparts

shaft h7
housing H7
bearing inner diameter C7 (decreases down to D8 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 > 155 HB
