GX 70 F
Thrust spherical plain bearing, maintenance-free, metric sizes
Thrust spherical plain bearings are designed to accommodate axial and combined radial and axial loads.
This specific design includes a steel/PTFE FRP sliding contact surface combination that is maintenance-free. However, relubrication, which can be applied from both sides, can extend bearing service life.
- Designed for axial and combined radial and axial loads
- Separable shaft and housing washers enable easier mounting
- Long service life and maintenance-free
- Relatively insensitive to contaminants
- Low coefficient of friction
