Family specifications and selection conditions
| Product description | Radial spherical plain bearings are designed to accommodate radial and combined radial and axial loads, and also misalignment. This specific design includes 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. |
|---|---|
| Manufacturer features | Designed for radial and combined radial and axial loads • Long service life • Minimal maintenance • Suitable for heavy static, alternating or impact loads |
