Axial Deep Groove Ball B. SKF 51408

SKF axial deep groove ball bearing 51408: A single-direction rolling bearing made from 100Cr6, with dimensions of 40x90x36 mm, for purely axial loads in mechanical engineering.

The SKF 51408 axial deep groove ball bearing is a separable rolling bearing designed to accommodate axial forces in one direction. With a bore of 40 mm, an outside diameter of 90 mm and a height of 36 mm, this component provides axial support for shafts. Manufactured from standard roller bearing steel (100Cr6), the raceways offer high dimensional stability. In combination with the guided sheet steel cage, the bearing unit is designed for operating temperatures between –30 and +150 degrees.

What is the 51408 single-direction axial deep groove ball bearing suitable for?

This axial deep-groove ball bearing exclusively absorbs axial forces acting on the bearing axis from a single direction. Under no circumstances should this model be subjected to radial loads in the design; therefore, a separate radial bearing arrangement must be provided. The application range covers bearing arrangements with predominantly single-direction axial forces. As the design is not angularly adjustable, installation requires plane-parallel, rigid mating surfaces on the shaft shoulder and housing to prevent edge loading on the rolling elements.

What is important to consider during installation and with regard to tolerance class P0?

Manufactured to tolerance class P0/PN (corresponding to ABEC 1), the bearing meets all standard requirements regarding dimensional and running accuracy. As this product range comprises only the axial deep-groove ball bearing without a washer, the mounting surfaces on the housing must be perpendicular to the shaft. Any misalignment caused during manufacture cannot be compensated for in this rigid design. As an open component without integrated seals, the bearing requires an application-specific surrounding structure with lubricant as well as external protection against contamination.
