In order to from the structure, size large, the market requires the use of INA bearings of various mechanical devices, instruments, performance is more and more strict. Bearing selection of the most appropriate, need to study from various angles. Selection of bearing, in general, allowing for bearing arrangement, shafting device, assembly difficulty, INA bearing space, size and bearing market, largely determines the bearing structure.
The deformation of the measures, such as the use of rotating hardening, die quenching, control components into the oil way, the potential of volatile materials; on the other hand, is to improve the automation level and the stability of heat treatment, and fully guarantee the stability and optimization of the process, product quality dispersion is very small (or zero), carbon and nitrogen special nitriding quenching, increase the content of residual austenite in appearance, improve the appearance of stress state, greatly improving the gearbox carbonitriding, base surface hardness increased on the appearance of residual austenite content is not reduced, should be grinding technology, measurement technology, fault diagnosis technology, should be combined with the specific equipment and product research on the deformation.
Greatly improve the accuracy and service life of wear on bearing performance, such as the use of vapor deposition diamond coating is coated on the raceway in INA bearing can reach antifriction, wear resistance effect. If INA bearing inner sleeve is cracked in trouble, we bought the best quality INA bearings to use, also need to use the best inner sleeve, if not the best INA bearing inner sleeve that how to do, if the sets of fragmentation, the inside of the bearing damage that only cry bitterly, that please God also don't use.
Therefore, INA bearing life expectancy isothermal quenching than the customary fire quenched and significantly improve the reliability. This technology is widely used in railway bearings, rolling mill bearings and use in special conditions of INA bearings
