SKF 62214-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 70x125x31mm

The SKF 62214-2RS1 wide-series sealed deep groove ball bearing provides rotational support in machinery where an extended bearing seat is required without increasing the shaft or housing diameter. Its 31mm width distinguishes it from the conventional 6214 bearing, which measures 24mm wide despite sharing the same 70mm bore and 125mm outside diameter. This additional axial width affects shaft shoulders, spacers and bearing retention arrangements, so the two versions are not direct dimensional substitutes. Its single row deep groove raceways accommodate predominantly radial loads and axial forces in either direction, subject to operating limits. SKF specifies a basic dynamic load rating of 60.5kN and a basic static load rating of 45kN, providing essential figures for bearing life and load calculations.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining grease and restricting the entry of dust, moisture and debris. This makes the design useful in enclosed drive assemblies where routine relubrication is difficult. SKF lists a limiting speed of 3,400rpm for this configuration, although suitable continuous operation also depends on loading, temperature and contact seal friction. Normal (CN) radial internal clearance requires carefully selected shaft and housing fits to maintain appropriate clearance after mounting. When replacing an existing bearing, verify the complete designation and 31mm width, particularly where similar machinery uses the narrower 6214 series. Correct alignment and mounting forces applied to the fitted ring help avoid damage during installation.
