SKF/Global Angular Contact Spherical Plain Bearings

Angular contact spherical plain bearings have sphered sliding surfaces on the inner and in the outer ring which are arranged at an angle to the bearing axis. They are therefore particularly suitable for carrying combined (radial and axial) loads. A single angular contact spherical plain bearing can only accept axial loads acting in one direction. Under radial loads, a force acting in the axial direction is produced in the bearing which must always be opposed by an equal force acting in the opposite direction. Therefore, the bearings are usually adjusted against a second bearing. If two angular contact spherical plain bearings are arranged so that their sphere centres coincide, a spherical plain bearing is obtained which can accommodate heavy radial loads as well as heavy axial loads in both directions.
