SKF 62204-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 20x47x18mm

The SKF 62204-2RS1 wide-series sealed deep groove ball bearing provides rotational support in machinery where the bearing seat is designed for an 18mm axial width. Its extended profile is the key distinction from a conventional 6204, which shares the same 20mm bore and 47mm outside diameter but measures only 14mm wide. This difference affects the positioning of spacers, shoulders and retaining components, making the two bearings unsuitable as direct dimensional substitutes. The single row deep groove construction supports radial loads and axial forces in either direction within its rated limits. SKF specifications give a basic dynamic load rating of 12.7kN and a basic static load rating of 6.55kN. These figures should guide bearing selection rather than assuming the wider profile provides greater carrying capacity.

The 2RS1 rubber contact seals provide protection on both faces, retaining the factory grease and helping exclude airborne dust, dirt and moisture. This reduces routine lubrication requirements in enclosed transmission and material-handling equipment. SKF specifies a limiting speed of 10,000rpm for the sealed design, although continuous operating conditions must account for loading, temperature and friction at the contact seals. The bearing has normal radial internal clearance, so shaft interference fits and thermal expansion must be considered during installation. For replacement work, confirm the complete designation, particularly the 62204 series number, sealing arrangement and 18mm width.
