FAG Needle Roller Bearings Guide

Product Description

The NKS28-XL FAG machined needle roller bearing consists of a machined outer ring with two ribs, needle rollers, and a cage, without an inner ring. The needle rollers run directly on a suitably hardened and ground shaft raceway, which helps minimize radial installation space. Its compact design provides high radial load capacity and rigidity, while the cage guides the needle rollers to reduce friction and support high-speed operation. In addition, X-life provides higher load ratings, increased reliability, and longer operating life.

The NKS28-XL bearing is suitable for printing and packaging, industrial transmissions, machine tools, automotive, food processing, and general mechanical engineering. Its high radial load density and compact cross-section are particularly useful where installation space is limited. Meanwhile, the combination of high radial load capacity, low friction, high-speed capability, and long service life supports efficient operation in compact mechanical systems.
