Axial Deep Groove Ball B. FAG 51208

The FAG 51208 axial deep-groove ball bearing, with dimensions of 40x68x19 mm, is designed to accommodate unidirectional axial forces in mechanical engineering applications.

The 51208 axial deep-groove ball bearing is designed to specifically accommodate unidirectional axial forces in shaft guides. With a bore of 40 mm, an outside diameter of 68 mm and a width of 19 mm, this design is suitable for standardised mounting spaces. FAG manufactures this bearing from standard rolling-bearing steel (100Cr6) with a guided sheet steel cage. The manufacturing accuracy complies with tolerance class P0/PN or ABEC 1, thereby ensuring that defined mounting dimensions in mechanical engineering are maintained.

What requirements does the 51208 axial deep-groove ball bearing meet in operation?

The component is used in bearing arrangements where purely axial forces must be absorbed in a defined direction and no radial loads act on the bearing. For combined forces, separate radial bearings must be provided. With a thermal rating suitable for operating temperatures ranging from -30 to +150 degrees, the component operates in industrial environments with continuous axial load-bearing.

What characterises the design of this single-acting axial bearing?

The design specifically supports shaft forces in one direction and consists of separately mountable discs. As the bearing is not angularly adjustable and is designed without a shim, the design requires precisely perpendicular and rigid mating surfaces on the housing and shaft. Misalignment or skewing cannot be compensated for. The integrated sheet steel cage guides the rolling elements evenly between the housing and shaft discs.
