SKF 62310-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 50x110x40mm

The SKF 62310-2RS1 sealed extra-wide deep groove ball bearing provides rotational support in equipment designed around a 40mm bearing width. Its 50mm bore and 110mm outside diameter match those of a standard 6310 bearing, but its wider construction requires a different axial mounting arrangement. SKF specifies a basic dynamic load rating of 61.8kN and a basic static load rating of 38kN, making these figures essential when evaluating fatigue life and peak loading. The single row deep groove raceways accommodate predominantly radial loads alongside axial forces in either direction, subject to the bearing's rated limits. Its wider profile should not be interpreted as an automatic increase in load capacity over other bearings with matching bore dimensions.

The 2RS1 rubber contact seals retain factory-applied grease and help shield the rolling elements against dust, moisture and other external contaminants. This is useful in industrial drive and transmission assemblies where frequent relubrication access is restricted. SKF lists a limiting speed of 4,300rpm for this configuration, although continuous running suitability depends on bearing load, operating temperature and friction generated by the contacting seals. Normal radial internal clearance requires carefully selected shaft and housing fits to preserve adequate clearance after installation. When replacing an existing bearing, verify the complete designation and 40mm width, as bearings with the same 50mm bore may differ significantly in outside diameter, width and load ratings.
