SKF 6224-2RS1/C3 Rubber Sealed Single Row Deep Groove Ball Bearing 120x215x40mm

The SKF 6224-2RS1/C3 sealed deep groove ball bearing provides reliable rotational support for heavy industrial equipment using a 120mm shaft. With a 215mm outside diameter and 40mm width, its substantial 62 series construction is designed to withstand significant radial loads while accommodating axial forces in either direction within its rated limits. SKF specifies a basic dynamic load rating of 146kN and a basic static load rating of 118kN, making these values important when calculating bearing life and assessing sustained or stationary loads. The single row design uses a pressed steel cage to separate and guide the rolling elements. Its dimensions must be matched to the existing shaft, housing and locating shoulders during replacement.

The 2RS1 contact seals are fitted on both sides of the bearing, retaining grease and restricting the ingress of dirt, moisture and other contaminants. This arrangement reduces routine lubrication requirements in enclosed machinery, although surrounding seals and maintenance conditions must still be considered. The C3 suffix identifies greater-than-normal radial internal clearance, allowing additional initial clearance for installations where interference fits or temperature differences reduce the clearance during operation. C3 is not automatically preferable in every application; the correct clearance depends on the actual mounting and running conditions. SKF lists a 1,900rpm limiting speed for this sealed bearing, so designers must assess rotational speed alongside loading, temperature and seal friction. Its approximate weight of 5.36kg also calls for appropriate handling and installation equipment.

Typical Applications:

Heavy-duty industrial electric motors

Large conveyor drive and pulley assemblies
