GEZ 012 ES
Radial spherical plain bearing, requiring maintenance, inch sizesRadial 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. The bearings require maintenance and can be relubricated via lubrication holes and an annular groove in both rings.
- Designed for radial and combined radial and axial loads
- Suitable for heavy static, alternating or impact loads
