Bearing Numbering System

Metric bearings are usually quoted with a 3, 4 or 5 digit code. Deciphering these codes is not straightforward and requires a lookup table. However, this short video on youtube describes the numbering system for the vast majority of bearings associated with bicycles.

Bearing Sizing

Bearings are measured and usually quoted by their size. This is expressed as the inner diameter x outer diameter x thickness (width). These dimensions are usually quoted in mm. Please refer to the drawing below for a schematic of the dimensions.
