FAG Needle Roller Bearings Guide

Product Description

The NKI9/12-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 bearing raceway. Its compact needle roller design provides high radial load capacity and rigidity within a small radial cross-section. In addition, X-life provides higher load ratings, improved reliability, and longer operating life, supporting efficient operation in space-saving bearing arrangements.

The NKI9/12-XL bearing is suitable for automotive, industrial transmissions, machine tools, printing and packaging, agricultural 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 makes it suitable for compact mechanical systems requiring efficient radial support.
