Axial Deep Groove Ball B. FAG 51210

The FAG 51210 axial deep-groove ball bearing, with dimensions of 50 × 78 × 22 mm, accommodates pure axial loads from one direction.

The FAG 51210 axial deep-groove ball bearing is a single-acting thrust bearing made from standard rolling-element steel (100Cr6). It is specifically designed to absorb axial forces and supports the shaft on one side. Due to its design, this bearing must not be subjected to radial loads. With a bore of 50 mm, an outside diameter of 78 mm and a width of 22 mm, it is suitable for industrial applications requiring axial guidance. The sheet steel cage guides the rolling elements at operating temperatures ranging from –30 to +150 degrees.

What is the 51210 axial deep groove ball bearing suitable for?

This rolling bearing is suitable for designs in which only axial forces in one direction are present. Typical applications are found in general mechanical engineering for bearing arrangements with a defined axial thrust direction. As the bearing is not angularly adjustable, it requires plane-parallel and perpendicular contact surfaces on the housing and shaft. The single-acting design absorbs axial thrust forces and allows separate mounting of the shaft flange, housing flange and ball-cage assembly.

What are the key considerations for the 51210 bearing design?

Before installation, check the exact pairing of the shaft washer and housing washer. The shaft washer has a ground bore for guidance on the shaft, whilst the housing washer has radial clearance within the housing. This version is supplied without a washer and complies with tolerance class P0/PN or ABEC 1. When designing the assembly, ensure there is an external seal and a continuous supply of lubricant, suitable for the temperature range from -30 to +150 degrees.
