FAG Needle Roller Bearings Guide

Product Description

The NKX30-Z-XL INA combined bearing consists of a radial needle roller bearing and a single-direction axial deep groove ball bearing, without an inner ring. The radial needle rollers run directly on a suitably hardened and ground shaft raceway, helping minimize radial installation space. The needle roller component supports high radial loads, while the cage-guided axial ball component supports axial loads in one direction. Moreover, the cage-guided ball set supports higher speeds than a full-complement axial ball design.

The NKX30-Z-XL is suitable for machine tools, industrial transmissions, printing machinery, automation, material handling, and general mechanical engineering. Its combined construction supports radial and axial forces within a compact bearing arrangement. In addition, the compact dimensions, high radial load capacity, axial support, and high-speed capability make it suitable for space-saving mechanical systems with combined loads.
