FAG Needle Roller Bearings Guide

Product Description

The NKIA5902-XL INA combined bearing consists of a radial needle roller bearing, an angular contact ball bearing as the axial component, and a single-piece inner ring. The needle roller section supports high radial loads, while the angular contact ball bearing supports axial loads in one direction. Its compact radial cross-section saves installation space and supports high-speed operation. In addition, X-life improves load carrying capacity and extends operating life.

The NKIA5902-XL bearing is suitable for machine tools, industrial transmissions, printing machinery, automation, material handling, and general mechanical engineering. Its combined design supports radial and single-direction axial loads within one compact bearing arrangement. Meanwhile, the combination of high load capacity, compact dimensions, rigidity, and high-speed capability supports efficient operation in demanding mechanical systems.
