In order to obtain the required organization and performance, the need for a quenching treatment. After cooling the workpiece to obtain martensite organizations, the cooling rate must be greater than the critical cooling rate, but too-rapid cooling rate and transformed the dramatic volume shrinkage of the workpiece, causing a great deal of stress. Conditions for obtaining the martensite "f", the cooling rate should be as low as possible.
Correctly restored one-way roller bearing performance with new bearings of the same. Clearance of rolling bearings for precision parameter can be reached, including those of the new requirements, it is important to understand and identify damage degree to choose the correct fix. Surface grinding process can clear some minor damage, but failed to clear the real tire, SAG or wear caused by failed to clear debris. Therefore, if only for surface grinding process of rolling bearings, rolling bearings generally not suitable for injury severity. And if it has been completely remanufactured repair technology, fatigue of the rolling bearing layer is completely removed, and rolling to a full replacement, cages are full finishing, which can meet the new bearing of rolling bearing performance requirements.
