FAG Spherical Roller Bearings Guide
Product Description
The 21311-E1-XL FAG spherical roller bearing consists of an inner ring, outer ring, two rows of symmetrical spherical rollers, and cages. Its self-aligning design compensates for angular misalignment and shaft deflection while supporting high radial loads and axial loads in both directions. The E1 design increases load carrying capacity, while X-life improves rolling contact conditions, reduces friction, and extends bearing service life.
The 21311-E1-XL bearing is suitable for paper machinery, material handling, mining and cement, industrial transmissions, agricultural machinery, and general industrial equipment. Its high load capacity and self-aligning capability make it suitable for applications exposed to heavy loads, vibration, shaft deflection, and alignment deviations.
