Axial Deep Groove Ball B. SKF 51240 M

The SKF 51240 M axial deep groove ball bearing accommodates unilateral axial forces with a bore diameter of 200 mm, an outer diameter of 280 mm and a height of 62 mm.

The SKF 51240 M axial deep-groove ball bearing is a separable rolling bearing made from standard bearing steel (100Cr6) designed to accommodate purely axial loads. It supports rotating shafts against axial thrust forces in one direction. The shaft ring, housing ring and ball-retaining brass cage can be fitted separately. Manufacture to the standard tolerance P0/PN (ABEC 1) ensures a defined fit on the connecting structure in industrial machinery.

What is the 51240 M axial deep groove ball bearing suitable for?

This design is used where assemblies with a 200 mm shaft diameter must accommodate heavy axial loads in a single direction. As single-direction axial deep groove ball bearings cannot transmit radial forces, the radial guidance of the shaft is always provided by a separate radial bearing. The flat housing flange requires a precisely perpendicular contact surface on the housing to enable even load distribution across the ball set.

What are the characteristics of the solid brass cage?

The suffix ‘M’ denotes a solid brass cage, which guides the rolling elements stably even under dynamic load peaks. Brass exhibits good emergency running properties and absorbs shocks and vibrations during operation. In combination with 100Cr6 rolling bearing steel, the component is designed for operating temperatures ranging from -30 to +150 degrees. When designing the application, please note that this bearing is not angle-adjustable and that the product scope does not include shims.
