Deep Groove Ball Bearings SKF 6212

The SKF 6212 deep groove ball bearing, with dimensions of 60x110x22 mm, is designed for predominantly radial loads in open arrangements.

The single-row deep groove ball bearing 6212 primarily accommodates radial forces as well as axial loads in both directions. Manufactured from standard rolling-element bearing steel (100Cr6) and fitted with a lightweight sheet steel cage, this design is suitable for operating temperatures ranging from –20 to +120 degrees. Manufactured to SKF’s Explorer performance class, it complies with the specifications of tolerance class P0/PN or ABEC 1. This makes the design suitable for demanding industrial applications with standardised mounting conditions.

In which applications is the open deep-groove ball bearing 6212 used?

This radial ball bearing is typically used in enclosed assemblies in mechanical engineering where there is a housing-side seal and an external lubrication supply. As the cylindrical outer ring has no groove or flange, the bearing fits flush into precise housing bores. The open design allows unimpeded circulation of lubricating oil or grease directly to the raceways, whilst minimising frictional resistance within the system.

What are the key features of the 6212 bearing with standard radial clearance?

The open design without integrated sealing washers is particularly recommended for applications that are already protected externally against dirt and moisture. By eliminating contact sealing lips, friction is kept to a minimum, which helps to minimise temperature rise at higher speeds. This model is fitted with standard radial clearance and is therefore designed for applications with conventional fit combinations and a constant operating temperature.
