NADELLA - ARNB75155/1

Details

Types ARNB combined bearings and their derivatives consist of a radial needle bearing with cage, in an outer race, with a high radial thickness, each face of which acts as a raceway for a needle or roller thrust bearing. The inner ring, secured laterally between the thrust plates, acts as the inner radial raceway. These bearings which take up very little space, are particularly recommended tor shafts requiring very precise axial positioning, operating under high load, such as leading spindles, ballscrews for numericallycontrolled machine tools, drive shafts on control apparatus, etc. Type ARNB bearings, they are usually blocked by a spacer positioned lengthways during assembly.
