Axial Deep Groove Ball B. FAG 51318

The FAG 51318 axial deep-groove ball bearing, measuring 90 × 155 × 50 mm, accommodates high unilateral axial forces in machinery and drive systems.

The FAG 51318 axial deep-groove ball bearing is designed as a separable rolling bearing for the specific purpose of accommodating axial forces acting from one side. With a bore of 90 mm, an outside diameter of 155 mm and a height of 50 mm, this design is suitable for heavy-duty shaft mountings. It is manufactured from hardened standard roller bearing steel 100Cr6, ensuring high dimensional stability. Thanks to its modular design, you can fit the shaft ring, housing ring and ball-cage ring separately.

What is the 51318 axial deep-groove ball bearing suitable for?

The component is primarily used where pure axial loads from a single direction need to be supported and no significant radial forces act on the axial bearing. Typical applications include vertical shaft arrangements and mechanical guides subject to purely axial loads. As the bearing is not angularly adjustable, the design requires a rigid mounting environment with perpendicular contact surfaces to prevent edge pressure on the raceways.

What is important when installing the 51318 thrust bearing?

During assembly, the precise alignment of the shaft washer and housing washer is crucial. The shaft washer has the tighter bore and sits firmly on the shaft, whilst the housing washer has a slightly larger bore so that the shaft can pass through without contact. The bearing is manufactured to standard tolerances (P0/PN or ABEC 1) and features a dimensionally stable sheet steel cage. The permissible operating temperature range is between -30 and +150 degrees Celsius.
