FAG Needle Roller Bearings Guide

Product Description

The NKIS40-XL FAG machined needle roller bearing consists of a machined outer ring with two ribs, an inner ring, needle rollers, and a cage. The inner ring provides a precision raceway where the shaft cannot serve directly as a rolling bearing raceway. Its needle roller design combines a compact radial cross-section with high radial load capacity and rigidity, while the cage guides and separates the rollers to reduce friction and support high-speed operation. In addition, X-life increases load ratings and extends service life.

The NKIS40-XL bearing is suitable for industrial transmissions, machine tools, automotive, agricultural machinery, printing and packaging, and general mechanical engineering. Its compact construction is especially useful where radial installation space is limited and a separate inner raceway is required. Meanwhile, the combination of high radial load capacity, rigidity, low friction, and high-speed capability supports efficient operation in compact and highly loaded mechanical systems.
