FAG Needle Roller Bearings Guide

Product Description

The NKXR50-XL INA combined bearing consists of a radial needle roller bearing and a single-direction axial cylindrical roller bearing, without an inner ring. The radial needle rollers run directly on a suitably hardened and ground shaft raceway, helping keep the radial cross-section compact. The needle roller component supports high radial loads, while the axial cylindrical roller component supports high axial loads in one direction. In addition, X-life improves load carrying capacity and extends operating life.

The NKXR50-XL is suitable for industrial transmissions, machine tools, printing machinery, material handling, automation, and general mechanical engineering. Its combined design supports radial and axial forces within a compact bearing arrangement, reducing the need for separate radial and thrust bearings. Moreover, the combination of high load capacity, rigidity, compact dimensions, and reliable axial support makes it suitable for highly loaded mechanical systems.
