Axial Deep Groove Ball B. SKF 51307

The SKF 51307 axial deep-groove ball bearing accommodates unilateral axial forces and has dimensions of 35 × 68 × 24 mm.

The 51307 axial deep-groove ball bearing is a separable rolling bearing designed to accommodate purely axial loads from a single direction. The assembly consists of a shaft ring, a housing ring and a guided ball set with an integrated sheet steel cage. Manufactured from standard rolling-element bearing steel (100Cr6), this design offers dimensional stability within a temperature range of –30 to +150 degrees. Thanks to its separable design, the individual components can be handled separately during assembly and maintenance work and fitted one after the other.

What is the 51307 single-direction axial deep-groove ball bearing suitable for?

Machine set-ups with a unidirectional thrust load along the axis constitute the primary area of application for this design. As the component is designed as a single-direction type, it absorbs axial forces exclusively from a defined direction. The bearing must not carry radial loads; these must be absorbed by additional bearings. Typical applications include vertical or horizontal shaft guides where pure axial forces act on the shaft flange without any interfering transverse forces.

What should be borne in mind when fitting the housing disc without a washer?

The flat housing disc in this design is not angle-adjustable. To ensure trouble-free operation, all contact surfaces on the housing and shaft must be precisely flat and aligned at right angles to the axis of rotation. Misalignment results in uneven point loads on the rolling elements. This model is designed without a shim and complies with tolerance class P0/PN or ABEC 1. The defined temperature range should always be taken into account when selecting a lubricant.
