FAG Needle Roller Bearings Guide

Product Description

The NK40/20-TV-XL FAG machined needle roller bearing consists of a machined outer ring with two ribs, needle rollers, and a PA66 plastic cage, without an inner ring. The needle rollers can run directly on a suitably hardened and ground shaft raceway, allowing a very compact radial design with high radial load capacity and rigidity. The TV cage guides and separates the needle rollers, helping reduce friction and support higher speeds. In addition, X-life improves load ratings, operating performance, and service life.

The NK40/20-TV-XL bearing is suitable for automotive, industrial transmissions, precision machinery, small electric drives, machine tools, and general mechanical engineering. Its small radial cross-section is particularly useful where installation space and component weight are limited. Meanwhile, the combination of high radial load density, low friction, and high-speed capability supports efficient operation in compact mechanical systems.
