FAG Needle Roller Bearings Guide

Product Description

The NK30/20-TW-XL FAG machined needle roller bearing consists of a machined outer ring, needle rollers, and a glass-fibre reinforced PA66 cage, without an inner ring. The needle rollers run directly on a suitably hardened and ground shaft raceway, helping reduce radial installation space. The TW design uses two short needle rollers in each cage pocket, providing stable roller guidance and efficient operation. Its compact construction offers high radial load capacity and rigidity, while X-life improves load ratings and extends service life.

The NK30/20-TW-XL bearing is suitable for industrial transmissions, machine tools, printing and packaging, textile machinery, food processing, and general mechanical engineering. Its compact radial design is particularly useful where installation space is limited. Meanwhile, the combination of high radial load capacity, rigidity, low friction, and high-speed capability supports efficient operation in compact mechanical systems.
