GEG 12 ESA
Radial spherical plain bearing, requiring maintenance, metric 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 and an extended inner ring. The bearings require maintenance and can be relubricated via lubrication holes and an annular groove in the outer ring.
- Designed for radial and combined radial and axial loads
- Suitable for heavy static, alternating or impact loads
- Extended inner ring can save spacer rings
