This angular contact ball bearing carries axial loads in a single direction, with a bore of 40.0 mm, outside diameter of 90.0 mm and width of 20.0 mm, and a net mass of 0.64 kg. It is fitted with a standard cage and has no screw mounting feature, so the outer ring is positioned directly against the housing without additional fixing elements. The bearing is supplied without sealing, so lubrication and protection against contamination need to be provided by the surrounding housing design. This single-direction axial contact arrangement suits shaft assemblies where axial load acts only one way and where a plain, non-screwed outer ring fit is required.
