GEH 70 ES-2RS

GEH 70 ES-2RS

Radial spherical plain bearing, requiring maintenance, sealed, metric sizes

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.

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
