FAG 20221-MB Barrel Roller Bearings 鼓形滚子轴承 105 × 190 × 36 mm

Overview

FAG 20221-MB Barrel Roller Bearing uses a single row of barrel-shaped rollers and a spherical raceway to tolerate misalignment. With self-aligning capability and high radial load capacity, it suits gearboxes, conveyors, and industrial shaft supports under medium to heavy loads.

Barrel-shaped rollers run between the inner ring raceway and spherical outer ring raceway. The single-row structure can be more compact in width than a spherical roller bearing, depending on the application.

Selection guidance

Review misalignment, radial load, presence of axial load, mounting width, lubrication, and speed range.
