Family specifications and selection conditions
| Product description | These radial spherical plain bearings have a steel/PTFE FRP sliding contact surface combination. They are factory greased and maintenance-free. However, relubrication can extend bearing service life and can be applied via lubrication holes and an annular groove in both rings. Compared to the GEC design (axially split outer ring), the GEP design (radially split) has a wider and larger outside diameter for a given shaft size. This results in a higher basic load rating, but a smaller tilt angle. |
|---|---|
| Manufacturer features | Designed for radial and combined radial and axial loads • Long service life and maintenance-free • Relatively insensitive to contaminants • Low coefficient of friction |
