SKF 625-2RS1 Rubber Sealed Single Row Deep Groove Ball Bearing 5x16x5mm

The SKF 625-2RS1 sealed miniature deep groove ball bearing supports 5mm rotating shafts in equipment where bearing dimensions must be kept to a minimum. Its compact single row construction accommodates predominantly radial loading alongside limited axial forces in either direction, provided the application remains within the bearing's rated capacity. This makes it useful for miniature motors, precision mechanisms and small transmission components where the direction of loading may vary. The SKF product specification lists a basic dynamic load rating of 0.936kN and a basic static load rating of 0.29kN. These relatively modest ratings underline the importance of assessing operating loads rather than choosing the bearing solely by its dimensions.

The 2RS1 rubber contact seals protect both faces of the bearing, retaining its grease fill and restricting the entry of dust, fine debris and moisture. This is particularly beneficial in miniature assemblies that cannot easily be dismantled for regular lubrication. The published limiting speed is 28,000rpm, although actual operating suitability depends on seal friction, loading and temperature. Normal (CN) radial internal clearance requires appropriately controlled shaft and housing fits, as interference can noticeably affect a miniature bearing's operating clearance. During fitting, apply mounting force to the ring being installed rather than through the balls. For replacement purposes, verify the 2RS1 contact-seal suffix and avoid confusing this bearing with the stainless steel W 625 variant.
