Deep Groove Ball Bearings FAG 6008

FAG 6008 deep-groove ball bearing, dimensions 40x68x15 mm, open design and sheet steel cage, for a wide range of industrial and repair drives.

The single-row deep groove ball bearing 6008 is a versatile rolling bearing designed primarily for radial loads. In rotating shafts, this design also accommodates axial forces in both directions. Manufactured from standard roller bearing steel (100Cr6) with raceways in the standard tolerance class P0/PN (ABEC 1), the bearing operates quietly. Due to its open design without integrated sealing washers, this version is particularly suitable for installation in enclosed housings with a central lubrication supply.

For which operating conditions is the 6008 deep groove ball bearing suitable?

This bearing is designed for applications with predominantly radial loads and moderate axial forces. As the outer ring has neither a flange nor a ring groove, the component can be fitted flush into cylindrical housing bores. The integrated sheet steel cage keeps the rolling elements at a uniform distance from one another. This design is particularly suitable for applications where existing oil lubrication or a lubrication area sealed on site provides a continuous supply to the rolling elements.

When is the open design of the bearing the right choice?

The open design offers low frictional resistance because there are no sealing lips on the inner ring that come into contact with it. Designs with oil bath or recirculating lubrication take advantage of this, as lubricating oil can circulate unhindered. At the same time, the open design requires protection against the ingress of external contaminants through the machine housing. With normal radial bearing clearance, the play corresponds to standard fit conditions at moderate operating temperatures between –20 and +150 degrees Celsius.
