Angular contact spherical plain bearings are designed to withstand combined radial and axial loads. Single bearings can withstand axial loads acting in one direction. This particular design includes a lubrication-free steel/PTFE FRP sliding contact surface combination. However, supplementary lubrication can be provided from both sides, thus extending the service life of the bearing.
