Axial Deep Groove Ball B. FAG 51308

The FAG 51308 axial deep-groove ball bearing (40x78x26 mm) accommodates unidirectional axial forces and is made from 100Cr6 rolling-element steel with a sheet steel cage.

The FAG 51308 axial deep-groove ball bearing is an open rolling bearing that guides shafts precisely in the axial direction. With a bore of 40 mm, an outside diameter of 78 mm and a height of 26 mm, this bearing supports purely axial forces. As it is manufactured from standard 100Cr6 bearing steel and features a guided sheet steel cage, the assembly is suitable for operating temperatures ranging from -30 to +150 degrees. The component is supplied as a bearing without a separate washer.

What is the 51308 axial deep-groove ball bearing suitable for?

This axial bearing absorbs axial forces from a single direction only and supports rotating shafts against axial thrust forces. However, the design must not be subjected to radial loads. Typical applications are found in general mechanical engineering in bearing arrangements where unilateral axial forces need to be absorbed. As the bearing is not angularly adjustable, trouble-free operation requires that the mating surfaces in the housing and on the shaft are machined exactly at right angles to the axis of rotation.

What are the key features of the 51308 axial deep-groove ball bearing?

As a single-direction version in tolerance class P0/PN or ABEC 1, the bearing consists of a shaft disc, a housing disc and the ball-guided sheet steel cage. As the discs have flat contact surfaces, this design does not automatically compensate for manufacturing-related misalignment errors. Planar-parallel abutment surfaces on the shaft shoulder and a careful supply of lubricant are therefore crucial. As the model is unsealed, you should provide an external housing seal against dirt and moisture, depending on the ambient conditions.
