Bearing Size Series

39 size series covering bore diameters from 1.5mm to 65mm + angular contact, thrust, self-aligning, spindle, inch R-series, miniature, thin section, airframe, track & more

📐 All dimensions follow ISO 15:2017 boundary dimension standards. The basic designation encodes the bearing type (first digit), width series (second digit), diameter series (third digit), and bore code (last two digits). Bore code × 5 = bore diameter in mm (e.g., 05 = 25mm, 08 = 40mm).
