Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate combined loads, i.e. simultaneously acting radial and axial loads. The axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis. Double row angular contact ball bearings SKF double row angular contact ball bearings design corresponds to two single row angular contact ball bearings arranged back-to-back. Bearing Features: Less axial space - Can be used for applications where two single row angular contact ball bearings arranged back-to-back take up too much axial space. Accommodates radial as well as axial loads in either direction. Accommodates tilting moments. Stiff bearing arrangement. Specifications Inner Diameter: 17mm Outer Diameter: 40mm Width: 17.5mm
