GE 25 C
Radial spherical plain bearing, maintenance-free, metric sizes
These spherical plain bearings have a steel/PTFE sintered bronze contact surface combination and are maintenance-free.
The sliding surfaces have to be externally protected from contaminants. These bearings are also available with a wider inner ring and a larger outside diameter (suffix GEH), which enable higher load ratings and larger tilt angles.
- Designed for radial and combined radial and axial loads
- Long service life and maintenance-free
- Suitable for heavy, constant direction loads
- Low coefficient of friction
- High operating temperatures
- High sliding velocities and small operating clearances
