Axial Deep Groove Ball B. SKF 51102

The SKF 51102 axial deep groove ball bearing accommodates pure axial loads in one direction, whilst featuring compact dimensions of 15 × 28 × 9 mm.

The SKF 51102 axial deep groove ball bearing is designed for applications where unilateral axial forces need to be supported. Manufactured from standard rolling bearing steel (100Cr6), this bearing offers dimensional stability within an operating temperature range of -30 to +150 degrees Celsius. The guided sheet steel cage maintains an even spacing between the rolling elements and guides the balls between the shaft and housing washers. Thanks to its separable design, the components can be fitted onto the shaft one after the other.

What loads does the 51102 axial deep-groove ball bearing accommodate?

This rolling bearing withstands purely axial thrust forces in one direction. It is used in designs to absorb axial forces acting on rotating shafts. As this is a single-direction design, the bearing supports the shaft in one direction only. Due to its design, this type of bearing cannot accommodate purely radial forces. If combined loads occur, radial forces must be absorbed by separate radial bearings.

What are the key considerations when installing the 51102 axial deep groove ball bearing?

The component is not angle-adjustable; the design is intended for installation without a shim. Parallel mounting surfaces on the housing and shaft shoulder are required to prevent misalignment and uneven point loads on the ball raceways. The shaft and housing washers have different internal diameters: the narrower washer sits on the shaft, whilst the wider washer is housed within the housing. Manufacture to standard tolerances (tolerance class P0/PN or ABEC 1) enables integration into standardised connecting parts.
