Detailed Photos

 

Angular contact ball bearings are nonseparable bearings with a defined contact angle in the radial direction relative to the straight line that runs through the point where each ball makes contact with the inner and outer rings. In addition to radial loads, angular contact ball bearings can accommodate single direction axial loads. Since an axial load is generated from a radial force, these bearings are generally used in pairs. Typically ideal for machine tools, feed screw mechanisms, ball screw support units, etc.
