Axial Deep Groove Ball B. FAG 51405

The 51405 axial deep-groove ball bearing accommodates axial loads on one side whilst maintaining compact dimensions of 25 × 60 × 24 mm.

The FAG 51405 axial deep-groove ball bearing is designed to support rotating shafts that transmit purely axial loads in one direction. Manufactured from standard rolling-bearing steel (100Cr6), the design features a guided sheet steel cage and operates within a temperature range of -30 to +150 degrees. As it is manufactured to tolerance class P0/PN or ABEC 1, the rolling bearing complies with current industry standards and is suitable for standardised mounting conditions in mechanical engineering.

What is the 51405 axial deep-groove ball bearing suitable for?

This axial bearing absorbs axial forces from one direction only and provides axial support for the mounted shaft. The component must not bear any radial loads, which is why designs usually incorporate separate radial bearings on the shaft. Typical applications are found in mechanical bearing arrangements where thrust forces act in one direction only. As the bearing is not angularly adjustable, the connecting parts must be manufactured to be plane-parallel and at right angles to the axis of rotation.

What should be taken into account when fitting and aligning bearing 51405?

Precise alignment is crucial during design and assembly. As this version is not angularly adjustable and is supplied without shims, misalignment or skewing will result in edge pressure and premature wear. The shaft disc and housing disc have different internal diameters: the shaft disc sits firmly on the shaft with its 25 mm bore, whilst the housing disc requires some clearance within the housing. Suitable lubrication within the temperature range of -30 to +150 degrees protects the rolling elements.
