Straight three-layer bearing with a copper-plated steel backing, a thin intermediate bronze layer, and a POM sliding layer on the inner surface. The sliding layer has lubrication pockets, which should be filled with grease before shaft installation.
This material is suitable for applications with relatively heavy loads and slow rotating, oscillating, or reciprocating motion. Additional lubrication is always recommended and extends the service life of the bearing.
Load:
Static 250 N/mm²
Dynamic 140 N/mm²
Oscillating 60 N/mm²
Maximum speed:
Lubricated: >2.5 m/s
Unlubricated: 2.5 m/s
Friction:
Boundary lubricated: 0.05–0.15 μ
Unlubricated: 0.15–0.25 μ
Tolerance:
Housing tolerance H7
Recommended shaft tolerance h8
Lubrication:
Additional lubrication is required and must be supplied via a grease groove in the shaft or housing.
All standard lubricants can be used. Avoid lubricants containing molybdenum disulfide (MoS₂) or graphite additives.
