Bearing arrangements are subjected to particularly high radial loads Not only very high radial forces but also high axial loads from one direction must be supported by the bearing position (semi‑locating bearing function) Bearing arrangements operating under the conditions described above must have very high rigidity Axial displacements of the shaft relative to the housing must be compensated without constraint in the bearing Very high radial loads occur at lower speeds, i.e. the bearings do not need to achieve speeds as high as those of cylindrical roller bearings with cage and particularly space-saving designs are required despite very high load The bearings should be separable (not self-retaining) for easier mounting
