Steel guide bushings with high-quality internal coating, selected from the best standardized products in addition to productions according to AlcoTech specifications. The PTFE-based sliding surface allows operation with a low coefficient of friction (minimized stick-slip effect) and reduces wear on the counter-surface.
Features:
- Static load limit: N/mm² 250
- Dynamic load limit: N/mm² 140
- 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
Application advice:
- Shaft tolerance: f7 – h8
- Housing tolerance: H7
- Shaft roughness: Ra, µm 0.05 - 0.5
- Shaft hardness: HB 300 – 600
