FAG Needle Roller Bearings Guide
Product Description
The NK42/20-XL FAG machined needle roller bearing consists of a machined outer ring, needle rollers, and a cage, without an inner ring. The needle rollers can run directly on a suitably hardened and ground shaft raceway, helping minimize radial installation space. Its compact design provides high radial load capacity and rigidity, while the cage guides the needle rollers and helps reduce friction. In addition, X-life provides higher load ratings, lower friction and operating temperatures, and longer service life.
The NK42/20-XL bearing is suitable for industrial transmissions, machine tools, printing and packaging, automotive, textile machinery, and general mechanical engineering. Its compact radial dimensions are 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.
