Bearing size reference
Spherical roller bearings: size tables
Two rows of barrel-shaped rollers with a spherical outer raceway: heavy loads plus misalignment tolerance.
Spherical roller bearings combine very high radial load capacity with tolerance for misalignment. They also take axial loads in both directions and are standard in heavy industrial machinery.
The 222 and 223 series correspond to dimension series 22 and 23. Suffixes describe the internal design (e.g. E, CC, CA), cage, lubrication features (e.g. W33) and a K for tapered bore.

Tapered rollers between a cone and a cup carry heavy combined radial and axial loads — the wheel-hub and gearbox workhorse.
Size tablesThrust ball bearings
Shaft washer, housing washer and a ball-and-cage assembly for purely axial loads in one direction.
Size tablesPillow block bearing units
