Bearing size reference
Deep groove ball bearings: size tables
The most common rolling bearing: one row of balls running in deep raceway grooves, available open, shielded or sealed.
Deep groove ball bearings carry radial loads and moderate axial loads in both directions. Their simple, non-separable design makes them the default choice in electric motors, pumps, gearboxes, fans and household appliances.
The designation starts with 6, followed by the dimension series (0, 2, 3 or 4 — light to heavy) and a two-digit bore code. Suffixes describe shields, seals, internal clearance and cage material, and the exact suffix letters differ from one manufacturer to another.

Miniature 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 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
UCP two-bolt pillow block units: a set-screw insert bearing (UC2xx) in a cast-iron P2xx housing, ready to bolt to a frame.
