The 5210.2RS.C3 RICH is a high-precision Double Row Angular-Contact Ball Bearing produced by RICH, engineered to handle significant combined loads—both radial and high axial loads in both directions. With dimensions of 50 x 90 x 30.2 mm, this bearing offers high stiffness and positional accuracy in demanding applications.
This bearing features double-sided rubber contact seals (2RS) for superior protection, effectively sealing the bearing against contaminants and retaining the internal lubricant for long, maintenance-free service life. The C3 internal clearance (greater than normal) is specified to ensure proper running clearance, especially under conditions involving high temperatures or where heavy press fits are applied. The inherent design, coupled with a robust steel cage, makes the 5210.2RS.C3 RICH ideal for pump applications, gearboxes, and machine tool spindles.
