Deep Groove Ball Bearings SKF 62304 -2RS1

The SKF 62304 -2RS1 deep groove ball bearing combines dimensions of 20x52x21 mm with seals that seal on both sides, making it suitable for demanding industrial applications.

The single-row deep groove ball bearing 62304 -2RS1 accommodates radial loads as well as axial forces in both directions. Manufactured from standard rolling-element bearing steel 100Cr6, this bearing type is characterised by a wider design of 21 mm compared with conventional bearings with the same bore diameter of 20 mm. The SKF version features a robust design with a sheet steel cage and is used in general mechanical engineering, drive technology and industrial maintenance.

What is the 62304-2RS1 deep groove ball bearing suitable for?

This radial ball bearing is particularly suitable for applications involving combined loads and where there are increased requirements for component protection. Thanks to its wider design, the bearing offers additional stability in the housing seat when subjected to radial forces. Typical applications include rotating machine shafts, bearing positions in conveyor elements and general industrial drives. The double-sealed design retains the lubricant inside the bearing and protects the raceways against the ingress of dirt and moisture. The bearing is therefore designed for low-maintenance assemblies in continuous operation.

What features does the 2RS1 seal offer in this bearing?

The seal, which makes contact on both sides, seals the interior containing the rolling elements against external contaminants. Compared with non-contact cover plates, sliding sealing lips provide effective protection against environmental influences, although they generate slightly higher friction during operation. The component covers an operating temperature range of -20 to +120 degrees Celsius and operates with standard radial bearing clearance in tolerance class P0 or ABEC 1. This facilitates integration into standardised fits on precision shafts and housing bores.
