FAG 20308-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 40 mm bore × 90 mm outside diameter × 23 mm width. Cylindrical bore.

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 203 section is wider and larger in outside diameter than a 20208 on the same 40 mm shaft, which buys longer rollers and higher radial capacity. The machined brass cage runs at higher speed and temperature than a pressed steel cage.
