- Scope
- This standard specifies the method for inspecting the circumference of thin-walled bearing bushes, the equipment and measuring tools necessary for measurement, in order to keep the height value within the range specified in GB/T 3162 and GB 7308, thereby ensuring that the bearing bush can be placed in the bearing seat. Achieve rated installation stress. Thin-walled bearings have an elastic tensor and are not cylindrical in the free state. Therefore, the bearing circumference can only be measured under forced load using special measuring equipment. Measuring equipment different from that shown in this standard can be used, but its measuring accuracy should meet the requirements of 16. This standard does not include the side IL of counterpart surface parallelism. This standard is applicable to thin-walled bearing bushes specified in TB/T 1435, GB/T 3162 and GB 7308.
