Super good quality imported bearings, so manufacturing is very troublesome. A lot of bearing manufacturers are not manufacturing, only to please the professional the manufacturing technician before production process imported bearings.grinding spindle
Different bearings may be used according to the the imported bearing parts of the chemical composition, shape, size and design requirements for the mechanical properties of the different method of quenching, each bearing steel has its fixed C curve, determines the choice of the bearing of the cooling medium after quenching gold phase microstructure and mechanical properties, so we must focus on considerations and specific analysis of the fact that many imported bearing parts generate heat treatment defects direct cooling bearing medium selection, but also with the specific operation.china bearing manufacturer
After the workpiece in the heat treatment furnace is heated to a fully austenitic, in order to obtain the desired microstructure and properties, the need for the quenching treatment. After cooling of the workpiece to obtain martensite, the cooling rate must be greater than the critical cooling rate, cold excessive speed so that the volume shrinkage of the workpiece and organizational changes violently, causing great stress. Therefore the cooling rate in the conditions to obtain martensite should be as low as possible, while the desired cooling curve in Fig.
Select a suitable quenching medium display is particularly important, it determines the organization and performance of imports bearing parts after quenching, quenching medium usually three kinds of solid, liquid and gas bearing quenching medium states of matter changes into fat biological state changes and developed biological state change class.sealed roller bearing
