Deep Groove Ball Bearings SKF 6208 N

The SKF deep groove ball bearing 6208 N (40x80x18 mm) features an integrated ring groove for space-saving axial retention in compact industrial housings.

The SKF 6208 N single-row deep groove ball bearing is designed primarily to withstand radial loads as well as moderate axial forces. Manufactured from standard 100Cr6 rolling bearing steel, this design features a ring groove on the outer ring. This open rolling bearing has no integrated sealing washers. This makes it particularly suitable for designs with an existing lubrication system or external housing seal. With standard radial clearance and a sheet steel cage, the bearing operates reliably in mechanical drives.

In which applications does the 6208 N deep groove ball bearing prove its worth?

It is primarily used in mechanical assemblies where confined installation spaces require a positive-lock axial retention. The ring groove on the outer ring allows the component to be secured directly in the housing bore using a suitable retaining ring. This eliminates the need for additional housing shoulders or spacer sleeves. Thanks to its open design, lubricant can reach the rolling elements and raceways unhindered during operation.

What is the function of the ring groove in the outer ring?

The designation ‘N’ indicates a precisely machined annular groove in the outer ring. This groove is used for axial fixation via a snap ring, which reduces the axial space requirement and simplifies the housing design. The bearing is manufactured to tolerance class P0/PN (corresponding to ABEC 1) and is designed for operating temperatures ranging from –20 to +150 degrees Celsius. In environments prone to contamination, an external seal must be fitted to the bearing housing.
