FAG Spherical Roller Bearings Guide

Product Description

The 21307-E1-XL-K-TVPB 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 provides increased load capacity, while X-life improves operating performance and service life. In addition, the tapered bore facilitates mounting, and the solid glass-fiber reinforced polyamide cages provide low mass and smooth operation. Schaeffler identifies K as a 1:12 tapered bore and TVPB as an inner-ring-guided solid polyamide cage.

The 21307-E1-XL-K-TVPB bearing is suitable for paper machinery, material handling, industrial transmissions, mining and cement, agricultural machinery, and general industrial equipment. Its high load capacity and self-aligning capability make it suitable for applications exposed to heavy radial loads, vibration, shaft deflection, and alignment deviations.
