Deep Groove Ball Bearings FAG 6008 -RSR

The FAG 6008-RSR deep-groove ball bearing, measuring 40x68x15 mm, offers compact dimensions and single-sided sealing protection for industrial shaft guides.

The FAG 6008-RSR deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) designed primarily to accommodate radial loads as well as moderate axial loads. The design combines a 40 mm bore with an outside diameter of 68 mm and a width of 15 mm. Fitted with a sheet steel cage and standard radial clearance, this bearing is suitable for applications in general mechanical engineering, as well as for gearbox and shaft mountings where a specific side needs to be protected against the ingress of dirt.

What is the FAG 6008-RSR deep groove ball bearing suitable for?

The bearing is primarily used in mechanical drive trains and housing designs where radial loads are the main consideration. Thanks to its manufacture to standard tolerances (P0/PN or ABEC 1), it fits precisely into standardised housing seats and shaft guides. The open rear side allows a continuous supply of lubricant from inside the housing, whilst the sealed side protects against external contamination.

What is the advantage of the single-sided RSR seal?

The single-sided sliding seal (RSR) shields the rolling elements from external dust or moisture, whilst the open opposite side allows contact with lubricant inside the housing. When designing the arrangement, users should take into account the temperature range of -30 to +100 degrees. The standard radial bearing clearance ensures uniform clearance between the inner and outer rings during operation without excessive frictional heating.
