Axial Deep Groove Ball B. FAG 51305

The FAG 51305 axial deep-groove ball bearing accommodates unilateral axial loads with a 25 mm bore, 52 mm outer diameter and 18 mm overall height.

The 51305 axial deep-groove ball bearing guides shafts axially and accommodates high axial forces from one direction. This FAG rolling bearing is made from standard rolling bearing steel (100Cr6) and features a dimensionally stable sheet steel cage. With compact main dimensions of 25 mm inner diameter, 52 mm outer diameter and a width of 18 mm, the bearing unit can be integrated into assemblies in a space-saving manner. The design complies with standard tolerance P0/PN or ABEC 1 and is suitable for operating temperatures ranging from -30 to +150 degrees.

What is the 51305 axial deep-groove ball bearing suitable for?

This rolling bearing is suitable for designs where purely axial forces need to be supported in one direction. However, the bearing must not bear purely radial loads; for this reason, users usually combine this component with separate radial bearings. Typical applications are found in general fixture and machinery manufacturing, where rotating components are fixed in a purely axial direction. The guided sheet steel cage keeps the rolling elements spaced apart and ensures smooth running characteristics during continuous industrial use.

What installation conditions does the non-angle-adjustable version require?

As the 51305 axial deep-groove ball bearing is not angularly adjustable, it is sensitive to misalignment between the shaft and the housing. It is essential that the contact surfaces of the housing and shaft flange are exactly perpendicular to the axis of rotation in order to avoid edge stresses. The scope of supply includes the axial deep-groove ball bearing without a washer. You should therefore design the connecting parts to be sufficiently flat and rigid. To ensure trouble-free operation, a minimum axial load must always be applied so that the balls roll smoothly within the cage.
