SKF 63005-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 25x47x16mm

The SKF 63005-2RS1 wide-section sealed deep groove ball bearing offers a compact radial footprint combined with additional axial width for equipment requiring a 16mm-wide bearing seat. Its 25mm bore and 47mm outside diameter match those of the standard 6005, but the 4mm width difference affects shaft shoulders, spacers and retaining arrangements. It must also be distinguished from the larger 6305 bearing, which has a 62mm outside diameter. Its single row deep groove raceways support predominantly radial loads and accommodate limited axial forces in either direction. The published basic dynamic load rating is 11.2kN, with a basic static load rating of 6.55kN. These figures should guide bearing selection rather than assuming extra width automatically increases carrying capacity.

The 2RS1 rubber contact seals protect both sides of the bearing, retaining factory-applied grease and helping restrict the entry of dust, dirt and moisture. This is useful in enclosed industrial mechanisms where access for regular relubrication is limited. SKF specifications list a limiting speed of 9,500rpm, although continuous operating conditions must also account for applied loads, temperature and friction from the contacting seals. The bearing has normal (CN) radial internal clearance, requiring suitable shaft and housing fits to maintain adequate clearance after mounting. During replacement, confirm the complete 63005-2RS1 designation and its 16mm width to avoid selecting a dimensionally incompatible 6005 or 6305 bearing.
