Axial Deep Groove Ball B. FAG 51212

FAG axial deep-groove ball bearing 51212: A single-direction rolling bearing with dimensions of 60 × 95 × 26 mm, designed to support shafts under purely axial loads.

The 51212 axial deep-groove ball bearing is a separable rolling bearing designed to accommodate axial forces acting in one direction. With a bore of 60 mm, an outside diameter of 95 mm and a height of 26 mm, this design guides shafts axially in one direction. Manufactured from standard roller bearing steel 100Cr6 and fitted with a dimensionally stable sheet steel cage, the design covers a wide temperature range from –30 to +150 degrees. It is manufactured to tolerance class P0/PN (equivalent to ABEC 1) to meet standard industrial requirements.

What loads can the 51212 axial deep-groove ball bearing withstand?

This bearing is primarily used in designs where significant axial thrust forces parallel to the shaft axis need to be supported. Typical applications are found in general mechanical engineering and plant construction. Important for design: Axial deep groove ball bearings are designed exclusively for axial loads and must not be subjected to radial forces. To accommodate combined loads, it is recommended to use separate radial bearings on the same shaft.

What are the key considerations for the non-angle-adjustable design?

The 51212 axial deep-groove ball bearing has flat housing discs and is not angularly adjustable. It cannot independently compensate for misalignment between the shaft and housing caused by manufacturing or assembly. Contact surfaces that are coplanar and exactly perpendicular to the axis of rotation are therefore essential for smooth running. During assembly, the shaft ring, housing ring and ball-cage assembly can be fitted separately. As this design does not include a shim, the bearing rests directly on the machined housing shoulders.
