INA Needle Roller Bearings Guide

Product Description

The NA4909-RSR-XL INA machined needle roller bearing consists of a machined outer ring with two ribs, an extended inner ring, needle rollers, and a cage. Its single-row design combines a compact radial cross-section with high radial load capacity and rigidity. The inner ring provides a precision raceway, making the bearing suitable where the shaft cannot serve directly as a rolling bearing raceway. In addition, X-life improves load carrying capacity and extends operating life.

The NA4909-RSR-XL features an RSR contact seal on one side, which helps retain lubricant and protect the rolling contact area against contamination. The bearing is suitable for industrial transmissions, automotive, agricultural machinery, machine tools, material handling, and general mechanical engineering. Its combination of compact dimensions, high radial load capacity, rigidity, sealing performance, and long service life supports reliable operation in demanding mechanical systems.
