FAG Needle Roller Bearings Guide

Product Description

The NKIB5910-XL INA combined bearing consists of a radial needle roller bearing and an axial angular contact ball bearing with a split inner ring. The needle roller component supports high radial loads, while the angular contact ball bearing supports axial loads in both directions. Its compact radial cross-section combines radial and axial load support in one bearing arrangement. In addition, X-life improves load carrying capacity and extends operating life. Schaeffler classifies the NKIB series as a combined needle roller/angular contact ball bearing for double-direction axial loads.

The NKIB5910-XL bearing is suitable for industrial transmissions, machine tools, printing machinery, automation, material handling, and general mechanical engineering. Its combined construction is particularly useful where radial installation space is limited and both radial and bidirectional axial forces must be supported. Meanwhile, the combination of high radial load capacity, bidirectional axial support, compact dimensions, and high-speed capability supports efficient operation in demanding mechanical systems.
