Bearing data summary
Bearing models generally have a front code, a basic code and a post code. In general, the bearing model is only indicated by the basic model. The basic model generally consists of three parts, type code, size code and inner diameter code. The post code is a letter, a number, etc., indicating the structure, tolerances, and special requirements of the bearing. The pre-code is used to indicate the sub-parts of the bearing and is represented by letters.
