GEG 20 ES

Radial spherical plain bearing, requiring maintenance, metric sizes

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 an extended inner ring. 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
Extended inner ring can save spacer rings
