FAG Needle Roller Bearings Guide

Product Description

The NKI30/20-TV-XL FAG machined needle roller bearing consists of a machined outer ring with two ribs, an inner ring, needle rollers, and a PA66 plastic cage. The integrated inner ring provides a precision raceway when the shaft cannot serve directly as a rolling bearing raceway. Its needle roller design provides high radial load capacity and rigidity within a compact radial cross-section. In addition, the TV cage guides and separates the needle rollers, helping reduce friction and support higher speeds, while X-life improves load ratings, operating performance, and service life.

The NKI30/20-TV-XL bearing is suitable for automotive, industrial transmissions, precision machinery, machine tools, agricultural machinery, and general mechanical engineering. Its compact dimensions and high radial load density make it suitable where installation space is limited but a complete inner raceway is required. Meanwhile, its combination of high radial load capacity, rigidity, low friction, and high-speed capability supports efficient operation in compact mechanical systems.
