The SKF 6210-2RS1/C3 sealed deep groove ball bearing provides dependable rotational support for machinery requiring a 50mm shaft bore and resistance to combined radial and moderate axial loading. Its single row deep groove raceways accommodate axial forces in both directions within the bearing's operating limits. SKF Explorer construction offers precision manufacturing and optimised internal geometry for demanding industrial applications. With a basic dynamic load rating of 37.1kN and a basic static load rating of 23.2kN, the bearing is suitable for consideration in motor shafts, pump assemblies and mechanical transmissions. The 90mm outside diameter and 20mm width should be checked against the existing housing, shoulders and locating arrangements before installation.
The distinguishing feature of this bearing is its C3 radial internal clearance, which is greater than normal and allows for a reduction in clearance caused by tight mounting fits or differential thermal expansion. C3 clearance is not automatically preferable for every installation; the correct selection depends on operating temperature, shaft and housing tolerances, and the required running clearance. The 2RS1 rubber contact seals retain factory grease and help exclude contaminants, making the bearing useful where frequent relubrication is impractical. SKF specifies a 4,800rpm limiting speed for the sealed configuration, subject to actual temperature and loading conditions. The bearing also features a sheet metal cage and bearing-steel rings. When replacing an existing bearing, verify the complete 6210-2RS1/C3 designation, as the normal-clearance 6210-2RS1 is not necessarily a suitable substitute.
Typical Applications:
Industrial electric motors with C3 clearance requirements
Centrifugal pumps and circulation equipment
Industrial fans and ventilation drive assemblies
Conveyor drive shafts and powered roller systems
Gearboxes and mechanical power transmission equipment
