Scope

This part of GB/T 7308 specifies the circumference measurement of thin-walled bearing bushes with or without flanges, in accordance with GB/T 27939, and describes the required inspection methods and measuring equipment.
Thin-walled bearing bushes are spring-loaded in a free state and are not cylindrical. Therefore, the circumference of the bearing bush can only be measured under a forced load using specialized measuring equipment.
Additionally, measuring equipment different from that illustrated in this part may be used, but its measurement accuracy must comply with the provisions of Chapter 17.
This part is applicable to the measurement of thin-walled bearing bushes with or without flanges, the specifications of which are specified in GB/T 7308.1.
