SKF 62211-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 55x100x25mm

The SKF 62211-2RS1 wide-series sealed deep groove ball bearing is specified for machinery needing a 25mm-wide bearing while retaining a 55mm shaft bore and 100mm outside diameter. A conventional 6211 shares these two diameters but measures only 21mm wide, so it cannot be substituted without checking the axial mounting arrangement. The difference affects housing shoulders, spacers and shaft retention components. Its single row deep groove design carries predominantly radial loads and accommodates axial forces in either direction within the bearing's operating limits. SKF publishes a basic dynamic load rating of 43.6kN and a basic static load rating of 29kN. These figures should guide selection because extra bearing width does not necessarily mean higher load capacity.

The 2RS1 rubber contact seals protect the bearing on both sides, retaining grease and restricting the entry of dust, moisture and other contaminants. This is useful in enclosed conveyor drives and transmission equipment where routine lubrication access may be difficult. SKF lists a limiting speed of 4,300rpm, although continuous operation must also account for load, temperature and contact seal friction. The bearing has normal radial internal clearance, so shaft interference fits and thermal expansion should be assessed to preserve appropriate clearance after mounting. For replacement work, verify the complete 62211-2RS1 designation and 25mm width. Applying installation force directly to the fitted ring also helps avoid damage to the rolling elements.

Typical Applications:

Industrial conveyor drive shaft assemblies

Enclosed mechanical power transmission systems

Material-handling and processing machinery

Industrial pulley and rotating equipment supports

Specialised machinery with 25mm-wide bearing seats
