SKF 6210-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 50x90x20mm

The SKF 6210-2RS1 sealed deep groove ball bearing provides rotational support for industrial machinery where a 50mm shaft must withstand combined operating loads within a compact bearing arrangement. Its single row deep groove design accommodates predominantly radial loads and moderate axial forces in either direction, subject to the bearing's operating limits. The 62 series offers greater load capacity than the narrower 6010 while requiring less installation space than the larger 6310. SKF specifications give a basic dynamic load rating of 37.1kN and a basic static load rating of 23.2kN. These values help engineers assess fatigue life and the suitability of the bearing for varying duty cycles rather than selecting a replacement based on shaft dimensions alone.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining factory-applied grease and restricting contamination from reaching the rolling elements. This is beneficial in enclosed electric motors, industrial pumps and mechanical drives where routine relubrication is inconvenient. The published limiting speed is 4,800rpm, although continuous operating suitability also depends on temperature, loading and friction generated by the contacting seals. Normal radial internal clearance distinguishes this version from the 6210-2RS1/C3, which has greater initial internal clearance. Correct shaft and housing fits are therefore essential to maintain suitable operating clearance after installation. When replacing an existing bearing, confirm the complete designation, including the specified seals and clearance.
