FAG 21315-E1-XL-TVPB-C3 Spherical Roller Bearing is a heavy-duty bearing that tolerates shaft misalignment and deflection through spherical raceways and barrel-shaped rollers. It supports high radial load and axial load in both directions, making it suitable for mining, steel, paper, wind, and other shock-prone equipment.
The outer ring has a spherical raceway, while the inner ring carries two rows of rollers guided by a cage. This self-aligning structure compensates for minor shaft and housing misalignment during operation.
Review load, speed, misalignment, lubrication method, bore type, and adapter sleeve requirements before selection.
