Description

NX combined roller bearings have no inner ring as the shaft is used as rolling groove: the shaft is grinded and hardened and has to have the same hardeness of needle rollers. When is not possible to harden the shaft the use of IR inner rings is required (see special tables). Should the bearings stand axial loads in two directions, a mounting of two bearings in opposition of the same series is required. The outer ring of a NX bearing is provided with a groove able to accept an elastic ring, which has the duty of stopping the bearings in case of axial loads. Excepted “Z” type, the above bearings can be oil or grease lubricated. Closed combined roller bearings are prelubricated before mounting in their axial part, whereas concerning radial part they must be lubricated, before beginning, with compatible grease.
