SKF 62307-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 35x80x31mm

The SKF 62307-2RS1 extra-wide sealed deep groove ball bearing is intended for machinery with a 35mm shaft and a housing designed to accommodate a 31mm-wide bearing. Its principal distinguishing feature is its axial width: a standard 6307 measures 35 x 80 x 21mm, making it unsuitable as a direct dimensional replacement. This additional width affects shaft shoulders, spacers, retaining components and the position of adjacent equipment. The single row deep groove construction carries predominantly radial loads and accommodates axial forces in either direction within its rated capacity. SKF specifies a basic dynamic load rating of 33.2kN and a basic static load rating of 19kN. These figures should be used for bearing life calculations rather than assuming that a wider bearing automatically has a higher load rating.

The 2RS1 rubber contact seals retain the factory-applied grease and help restrict the entry of dust, moisture and debris. This is advantageous in conveyor drives and enclosed mechanical assemblies where access for regular relubrication may be limited. SKF lists a limiting speed of 6,000rpm and a bearing mass of approximately 0.68kg. Actual continuous operating suitability depends on applied loads, temperature, lubrication conditions and contact seal friction. Normal radial internal clearance requires appropriate shaft and housing fits to preserve adequate clearance after mounting. When replacing an existing component, verify the complete designation, sealing arrangement and 31mm width to avoid selecting a dimensionally incompatible bearing.

Typical Applications:

Industrial conveyor drive and roller assemblies

Enclosed mechanical transmission equipment

Material-handling and processing machinery

Industrial shaft support and pulley mechanisms

Specialised equipment with 31mm-wide bearing seats
