FAG 20220-K-MB, 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 100 mm bore × 180 mm outside diameter × 34 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. The tapered bore sets radial clearance by drive-up distance rather than by interference fit alone. 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 20220K is an H220, whose shaft seat is 90 mm, one bore-code step below the bearing bore.
Alternate written forms of the same bearing: 20220-K-MB, 20220K.MB, 20220KMB, 20220K. The cylindrical-bore 20220MB is a related size on the same envelope with a different bore form. The 22220K is a double-row spherical roller bearing, a different bearing type.
