SKF 61810-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 50x65x7mm

The SKF 61810-2RS sealed thin section deep groove ball bearing is intended for compact rotating mechanisms where both bearing diameter and width are tightly constrained. Its exceptionally slender 618 series geometry provides shaft support while occupying considerably less space than conventional 60, 62 or 63 series bearings of the same bore. The single row ball construction accommodates radial loads and limited axial forces in either direction, within its rated capacity. SKF's corresponding 61810-2RS1 catalogue specification gives a basic dynamic load rating of 6.76kN, a basic static load rating of 6.8kN and a sealed limiting speed of 6,000rpm. These relatively low load ratings make accurate load calculations especially important, particularly where shock loads or substantial belt tension may occur.

The double rubber sealing arrangement helps retain the factory grease and restrict dust and moisture from entering the raceways. This is useful in enclosed mechanisms that cannot accommodate an external lubrication system. Contact seals create additional friction compared with an open bearing, so operating temperature and rotational speed must be considered during selection. Normal radial internal clearance requires careful attention to shaft and housing fits, as the thin rings can be distorted by excessive interference or poorly machined seating surfaces. For replacement work, verify the full manufacturer designation: SKF catalogue documentation commonly identifies this bearing as 61810-2RS1, while 61810-2RS is also used in commercial listings.
