- Allowable sliding speed: m/s 2.0 (p = 1.0)
- Coefficient of friction: m 0.02 - 0.25
- Operating temperatures: -200° / +280°C max
- High chemical resistance
- Thermal stability
- Maintenance-free
- Shaft tolerance: f7 – h8
- Housing tolerance: H7
- Shaft roughness: Ra, µm 0.05 - 0.5
- Shaft hardness: HB 300 – 600
