MT

Common materials and selection reference for QIBR four-point contact ball slewing bearings MT series in commercial applications：

The QIBR MT series four-point contact ball slewing bearings provide superior support in high-load environments. They can bear radial, axial, and overturning loads with non-gear and external gear options, ensuring optimal performance in rotating or swinging mechanical structures.

QIBR four-point contact ball slewing bearing MT series are usually made from 42CrMo and 50Mn materials, which have good wear resistance and strength for high-load application environments. In contrast, the material of 45 steel is suitable for applications with lighter loads.

Overall, the material selection of the slewing bearing MT series depends on the specific application requirements, including capacity, strength, environmental conditions, and other factors that ensure the life and performance of bearings when used. After considering those factors comprehensively, you can select the correct bearing for the application requirements.
