SKF 62209-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 45x85x23mm

The SKF 62209-2RS1 wide-series sealed deep groove ball bearing is specified for industrial assemblies requiring a 23mm-wide bearing on a 45mm shaft. Although it shares the 85mm outside diameter of a conventional 6209, its additional 4mm of width changes the positioning of shaft shoulders, spacers and retaining components. The two bearings should therefore not be treated as direct dimensional substitutes. Its single row deep groove raceways support predominantly radial loads while accommodating axial forces in either direction within the bearing's rated limits. SKF catalogue specifications give a basic dynamic load rating of 33.2kN and a basic static load rating of 21.6kN. These figures should guide bearing-life calculations rather than assuming that the wider construction automatically provides a higher load rating.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining factory-applied grease and helping restrict dust, moisture and debris from reaching the raceways. This is especially useful in enclosed conveyor and transmission assemblies with limited access for routine lubrication. SKF lists a limiting speed of 5,000rpm for this contact-sealed configuration, although actual operating suitability depends on loading, temperature and friction at the seals. Normal (CN) radial internal clearance requires suitable shaft and housing fits to preserve the required running clearance after mounting. For replacement work, verify the complete designation, 23mm width and sealing arrangement, and avoid transferring mounting forces through the rolling elements.

Typical Applications:

Industrial conveyor drive shaft assemblies

Material-handling and processing machinery

Enclosed mechanical transmission systems

Industrial pulley and roller mechanisms

Specialised shaft supports with 23mm-wide bearing seats
