SKF 6310-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 50x110x27mm

The SKF 6310-2RS1/C3 sealed deep groove ball bearing provides rotational support for industrial equipment operating with significant shaft loads and demanding mounting conditions. Its 50mm bore, 110mm outside diameter and 27mm width distinguish it from smaller 6210 and 6010 series bearings, making housing compatibility essential. The single row deep groove raceways accommodate primarily radial loads together with axial forces acting in either direction, subject to the bearing's rated limits. SKF specifies a basic dynamic load rating of 65kN and a basic static load rating of 38kN, providing useful figures for bearing life calculations, stationary load assessment and machinery design.

The 2RS1 rubber contact seals retain factory grease while helping prevent dust, moisture and other contaminants from reaching the rolling elements. SKF lists a limiting speed of 4,300rpm for this contact-sealed configuration, although continuous operation must also account for temperature, loading and seal friction. The distinguishing C3 clearance is greater than normal before mounting and can compensate for clearance reductions caused by tight interference fits or temperature differences between the bearing rings. It does not automatically make the bearing preferable for every application; operating clearance must suit the equipment design. The bearing also features a sheet metal cage and SKF Explorer performance classification. When replacing an existing bearing, confirm that the complete 6310-2RS1/C3 designation matches the original specification rather than choosing the normal-clearance 6310-2RS1 solely because its dimensions are identical.

Typical Applications:

Industrial electric motors requiring C3 bearing clearance

Heavy-duty conveyor drive and pulley assemblies

Agricultural machinery and mechanical transmissions

Industrial pumps and rotating equipment

Gearbox shafts and power transmission machinery
