FAG 20220-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 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, absorbing shaft deflection and housing misalignment without edge loading the rollers. Load is radial only. On a tapered bore the drive-up distance sets the final radial clearance, and C3 leaves room for that drive-up plus thermal growth of the inner ring.
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: 20220K.MB.C3, 20220-K-MB-C3, 20220KMBC3, 20220K. The cylindrical-bore 20220MB.C3 is a related size with a different bore form. The 22220K is a double-row spherical roller bearing.
