Sliding bearings are low-maintenance bushings and consist of three layers. The bushings are made of low-carbon steel, porous bronze and POM. In the internal sliding part, there are circular grease reservoirs (see photo) the reservoirs must be greased and oiled before installation. This is necessary to ensure optimal operation under relatively high loads at low speeds. These bushings are suitable for rotary and oscillating movements.

The advantages are:

- Noise and vibration absorption
- Re-lubrication is possible
- Possible hydrodynamic applications
- High loads
- Low wear and friction
- No water absorption
- Reduced clearance during operation
- Limited dimensions

Characteristics:
- Permissible load (dyn./stat.), N/mm2 120 (v ≤ 0.02) / 250
- Coefficient of friction m 0.02 ... 0.20

Application tips:
- Shaft tolerance f7 - h8
- Housing tolerance H7
- Shaft roughness Ra, mm 0 ... 0.8
- Shaft hardness, HB 150 - 600
