FAG Needle Roller Bearings Guide

Product Description

The NAO25×42×16-IS1-XL FAG machined needle roller bearing consists of a ribless machined outer ring, an inner ring, needle rollers, and a PA66 cage. Its single-row, ribless design allows the bearing components to be mounted separately and provides high radial load capacity and rigidity within a compact radial cross-section. The TV cage provides stable needle roller guidance, while the inner ring forms a precision raceway for the rolling elements. In addition, X-life improves load ratings, operating performance, and service life. Schaeffler lists this model specifically as a single-row NAO bearing with an inner ring and without ribs.

The NAO25×42×16-IS1-XL features an IS1 lubrication hole in the inner ring, which facilitates lubricant supply to the rolling contact area. It is suitable for industrial transmissions, machine tools, printing and packaging, textile machinery, automation, and general mechanical engineering. Its combination of compact dimensions, high radial load capacity, rigidity, and effective lubrication supports reliable operation in space-saving mechanical systems.
