Aligning needle roller bearings are units comprising drawn outer cups, plastic support rings with a concave inner profile, outer rings with a spherical outside surface, needle roller and cage assemblies and removable inner rings.The bearings can compensate static shaft misalignments and can thus tolerate misalignment of the shaft relative to the housing.Aligning needle roller bearings are firmly seated in the housing bore. The bore can therefore be produced easily and economically.
Aligning needle roller bearings are X-life bearings. In these bearings, the roughness and geometrical accuracy of the raceways have been optimised. This gives higher load carrying capacity and longer life.
