FAG Needle Roller Bearings Guide

Product Description

The NA4909-2RSR-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 provides high radial load capacity and rigidity within a compact radial cross-section. The inner ring provides a precision raceway for the needle rollers, making the bearing suitable where the shaft cannot serve directly as a raceway. In addition, X-life provides higher load carrying capacity and longer operating life.

The NA4909-2RSR-XL features contact lip seals on both sides, which help retain lubricant and protect the rolling contact area against contamination. It is suitable for industrial transmissions, automotive, agricultural machinery, construction machinery, material handling, and general mechanical engineering. The combination of high radial load capacity, rigidity, compact dimensions, effective sealing, and long service life supports reliable operation under demanding conditions.
