The sliding contact surface of these bearings is spherical and leans at a certain angle relative to the bearing centerline, which makes these bearings particularly suitable for combined (radial and axial) loads.
Angular contact plain bearings are designed to accommodate combined radial and axial loads. Plain bearings can accommodate axial loads in one direction.
This specific design includes a combined steel/PTFE FRP sliding contact surface that is maintenance-free. However, relubrication, which can be performed from both sides, can extend the economic life of the bearing.
