Thrust ball bearings: size tables
Shaft washer, housing washer and a ball-and-cage assembly for purely axial loads in one direction.
Single-direction thrust ball bearings carry axial loads in one direction only and must not be subjected to radial loads. They consist of a shaft washer, a housing washer and a ball-and-cage assembly, mounted separately.
Series 511, 512 and 513 increase in section height and load capacity for the same bore. Dimensions are bore d, outside diameter D and height H.

Deep groove ball bearings
The most common rolling bearing: one row of balls running in deep raceway grooves, available open, shielded or sealed.
Size tablesMiniature ball bearings
Small deep groove ball bearings with 3–9 mm bores — 608, 625, 688 and friends — used in skateboards, 3D printers, fans and small motors.
Size tablesSelf-aligning ball bearings
Two rows of balls with a common spherical outer raceway, tolerating shaft misalignment and deflection.
Size tablesAngular contact ball bearings
Raceways offset so that loads are carried at a contact angle, supporting combined radial and axial loads in one direction.
Size tablesCylindrical roller bearings
Cylindrical rollers with line contact for high radial load capacity; ring flanges determine axial guidance.
Size tablesSpherical roller bearings
Two rows of barrel-shaped rollers with a spherical outer raceway: heavy loads plus misalignment tolerance.
Size tablesTapered roller bearings
Tapered rollers between a cone and a cup carry heavy combined radial and axial loads — the wheel-hub and gearbox workhorse.
Size tablesPillow block bearing units
UCP two-bolt pillow block units: a set-screw insert bearing (UC2xx) in a cast-iron P2xx housing, ready to bolt to a frame.
