GE70-HO-2RS-C2 Radial Spherical Plain Bearings, Bore 70 Mm, Requiring Maintenance, Sealed
The GE70-HO-2RS-C2 Radial spherical plain bearings are widely used in hydraulic cylinder articulations of construction machinery (excavators, loaders), balance suspensions of heavy-duty trucks, linkage mechanisms of mining equipment, joints of agricultural machinery, and robot wrists—any application requiring swinging or tilting adjustments.
The GE70-HO-2RS-C2 bearing is a Radial spherical plain bearings with an inner diameter of 70 mm , an outer diameter of 105 mm, a width of 65 mm. bearing steel rings, bearing steel rolling mlement. Its dynamic radial rated load is approximately 313000 N, its static radial rated load is approximately 1560000 N. It uses C2 standard radial clearance, 2RS = Standard lip seals on both sides type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
GE70-HO-2RS-C2 bearings ( 70 mm x 105 mm x 65 mm) have the advantages of Capable of withstanding heavy loads and impacts, and featuring automatic self-aligning to compensate for centering errors, and are therefore widely used in the joints of construction machinery (such as excavators and cranes), hydraulic cylinder hinges, and suspension systems of heavy vehicles.

The GE70-HO-2RS-C2 Radial spherical plain bearings consist of an inner ring with a spherical outer surface and an outer ring with a spherical inner surface, forming a sliding spherical pair. Some models have a self-lubricating gasket (such as PTFE fabric) on the inner surface of the outer ring or the outer surface of the inner ring.
Radial spherical plain bearings can withstand heavy radial loads and impact loads, automatically compensating for angular alignment errors between the shaft and the bearing bore. The steel-to-steel type is heat-resistant, contamination-resistant, self-lubricating, maintenance-free, has a low coefficient of friction, and a long service life.
