The specification requirements for bearing rolling elements after bainite quenching can include the following:
1. Macro morphology of bainite quenching: According to relevant standards, the rolling body after bainite quenching should present a uniform and fine bainite structure. The bainite should be evenly distributed throughout the cross-section of the rolling body, without excessive aggregation areas or liquid precipitation.
2. Quenching hardness: The hardness of the rolling element after bainite quenching generally needs to meet certain standard requirements. Hardness testing can be conducted through methods such as Rockwell hardness, Brinell hardness, or Vickers hardness.
3. Hardness uniformity: The quenching hardness of the rolling element should have good uniformity, that is, there should be small differences in hardness at various positions throughout the rolling element to ensure consistent performance and lifespan.
4. Size and shape deviation of rolling element: According to design requirements and relevant standards, the size and shape deviation of rolling element needs to be within a certain range to ensure accurate matching and operating accuracy of bearings.
5. Surface quality: The surface of the rolling element should have good smoothness and smoothness, avoiding obvious scratches, abrasions, or rust on the surface.
These are only some common specification requirements, and specific bainite quenching specifications and requirements may vary depending on different bearing types, usage environments, and industry standards. Therefore, when conducting bainite quenching treatment, relevant standards and technical specifications should be referenced to ensure that the required performance and quality requirements are met.136-2180-8094
