Gear heat treatmentThe statement of gear heat treatment normally have two statement, normfalizing and tempering. The quenching of gear surface an processed according to customer's requirement, the hardness are in the range of 50HRC~60HRC. In different application, the gear quenching can divide into

what is a slewing bearing ?

The double row ball slewing bearing has two row steel balls for structure, it has bigger load capacity comparing to single row type slewing bearing and better safety factor, and it could bear axial load, radial load and tilting moment at the same time. Double row ball slewing ring has three seat rin

First of all, we should pay attention to three problems when we choose slewing bearing: load, bolt strength and whether the bolt hole is uniform.If the bearing is installed on the support surface which lacks integrity, local deformation will change the load, resulting in different load sizes of the

The slewing bearing has internal and external gears, and is usually processed by a gear hobbing machine or a gear shaping machine.
