FAG 20210-K-MB-C3, a single-row barrel roller bearing. One row of barrel-shaped rollers runs on a spherical outer raceway, so the inner ring, roller set and cage swivel inside the outer ring. Boundary dimensions 50 mm bore × 90 mm outside diameter × 20 mm width. Tapered bore, 1:12.

The barrel roller carries radial load and self-aligns on its spherical outer raceway, taking shaft deflection and housing misalignment without edge loading the rollers. Load is radial only. C3 clearance leaves running clearance after a tight shaft fit and after thermal growth of the inner ring. The machined brass cage runs at higher speed and temperature than a pressed steel cage.

1 Pc. Bearing only. Supplied without adapter sleeve.
A tapered-bore barrel roller seats on an adapter sleeve when it goes onto a plain cylindrical shaft; the sleeve for a 20210K is an H210, whose shaft seat is 45 mm, one bore-code step below the bearing bore.
Alternate written forms of the same bearing: 20210-K-MB-C3, 20210K.MB.C3, 20210KMBC3, 20210K. The cylindrical-bore 20210MB is a related size on the same envelope with a different bore form. The 22210K is a double-row spherical roller bearing, a different bearing type.
