Bearing size series code

The bearing size series code is a combination of the width (height) series code (one digit) and the diameter series code (one digit) of the bearing. The width (height) degree series code is on the left, the diameter series code is on the right, and two digits are combined to form the size series code.

(1) The diameter series refers to the series of outer diameter dimensions corresponding to the inner diameter of the same bearing, that is, the bearing of the same inner diameter has various outer diameters. There are 7, 8, 9, 0, 1, 2, 3, 4, 5 and other diameter series with successively increasing outer diameters.

(2) Width series refers to the width dimension series corresponding to the same bearing diameter series, that is, bearings with the same diameter series have different widths (or heights). There are 8, 0, 1, 2, 3, 4, 5, 6 and other width series with increasing width.

(3) The height series of thrust bearings correspond to the width series of radial bearings, and there are four height series with height dimensions of 7, 9, 1, 2 and so on.
