Deep Groove Ball Bearings SKF 625 -2RS1

The SKF 625-2RS1 deep-groove ball bearing has compact dimensions of 5x16x5 mm and, thanks to the double-sided lip seal, provides effective protection against contamination.

This single-row miniature deep-groove ball bearing is designed primarily to support radial loads as well as low axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, a dimensionally stable sheet steel cage guides the rolling elements at uniform intervals along the ground raceways. Thanks to its sealed design with contact seals on both sides, the bearing is suitable for compact mounting arrangements where dirt particles or moisture must be kept out of the interior and no additional housing seal is present.

What is the 625-2RS1 deep-groove ball bearing suitable for in practical applications?

Due to its small bore diameter of 5 mm, this rolling bearing is primarily used for small shaft diameters and compact bearing arrangements. The design with a cylindrical outer ring without a groove or flange allows for flush mounting in smooth housing bores. Furthermore, with a temperature range of –20 to +120 degrees, the bearing covers a wide range of everyday industrial applications, provided that no special thermal protection measures are required.

What are the advantages of the 2RS1 seal with contact on both sides?

The two sealing lips make contact with the inner ring’s contact surfaces under light pressure. This design protects the bearing interior from the ingress of solid foreign particles and splash water. At the same time, the seal helps to retain the lubricant within the bearing, thereby reducing the need for relubrication during operation. Together with the standard radial bearing clearance and tolerance class P0 (ABEC 1), this design enables precise shaft guidance.
