Family specifications and selection conditions
| Product description | These radial spherical plain bearings have a steel/steel sliding contact surface combination and a double-lip contact seal on both sides. The bearings require maintenance and can be relubricated via lubrication holes and an annular groove in both rings. Compared to the GE series, they have a wider inner ring and a larger outside diameter, which enable higher load ratings and larger tilt angles. |
|---|---|
| Manufacturer features | Designed for radial and combined radial and axial loads • Long service life • Minimal maintenance • Suitable for heavy static, alternating or impact loads • Enable larger tilt angles |
