Bearings by size

Find a bearing from its dimensions in mm: bore (d), outer diameter (D) and width (B, with T for tapered and H for thrust bearings). The index covers 631 sizes and 13,725 part numbers from SKF, FAG, NTN, NSK, RKB, TIMKEN, LINK-BELT, and KOYO; SKF part numbers appear in 585 of those sizes.

Most-listed sizes

Each size page gathers the catalog part numbers with those dimensions and splits them by bearing type, because deep groove ball, angular contact and cylindrical roller bearings can share a size yet not be interchangeable. Once you have the size, we quote by part number.

The dimensions follow the standards: ISO 15 for radial bearings, ISO 355 for tapered and ISO 104 for thrust. A basic designation measures the same in every brand; seals, internal clearance and cage are set by the suffix.
