INA Needle Roller Bearings Guide
Product Description
The RNA4910-2RSR-XL INA machined needle roller bearing consists of a machined outer ring with two ribs, needle rollers, and a cage, without an inner ring. The needle rollers run directly on a suitably hardened and ground shaft raceway, helping reduce radial installation space. Its single-row design provides high radial load capacity and rigidity within a compact cross-section. In addition, X-life offers higher load ratings, reduced friction, and longer operating life.
The RNA4910-2RSR-XL features 2RSR contact lip seals on both sides, which help retain lubricant and protect the rolling contact area from contaminants. This sealed design is suitable for industrial transmissions, automotive, agricultural machinery, construction machinery, material handling, and general mechanical engineering. Its combination of compact dimensions, high radial load capacity, effective sealing, and long service life supports reliable operation under demanding conditions.
