FAG Spherical Roller Bearings Guide

Product Description

The 21318-E1-XL-K+H318 FAG spherical roller bearing consists of an inner ring, outer ring, two rows of spherical rollers, cages, and an adapter sleeve. Its self-aligning design accommodates angular misalignment and shaft deflection while supporting high radial loads and axial loads in both directions. The E1 design provides increased load carrying capacity, while X-life improves operating performance and service life. In addition, the K tapered bore works with the H318 adapter sleeve, allowing secure mounting on cylindrical shafts and simplifying installation.

The 21318-E1-XL-K+H318 bearing is suitable for mining and cement, material handling, paper machinery, industrial transmissions, agricultural machinery, and general industrial equipment. Its high load capacity and self-aligning capability support applications with heavy loads and alignment deviations. Meanwhile, the adapter sleeve provides a practical and flexible mounting solution for cylindrical shafts.
