NTN bearing characteristics of the service life of superfinishing

Smooth operation. Superfinishing bearing for staggered checker in appearance, easy to save oil, not easy to wear, easy to fever and when grinding burn research phenomenon. Super finishing allowance of NTN bearing, an order of magnitude than grinding allowance is actually only a few microns. For low pressure feed processing. So the size of the superfinishing separation degree is small, high pass rate. Superfinishing bearing has a great track, and can transition from cutting disseminated to grinding, coarse degree can be quickly low appearance. But due to the vibration of its repeated change move towards, affect their further improve the quality of processing appearance. Superfinishing bearing not occur peak of the metamorphic layer, and is easy to wear, and also left by grinding metamorphic layers can be removed. To improve workpiece using life by 5 times. Floating bearing if used in harsh environment, bearing seal and seal cover is indispensable, because they can prevent dirt intrusion, extend the life of the bearing. In mill roll usually is supported by four columns sealed taper roller bearings. When using requirements under strong impact load, the intrusion of water and debris. Super capacity seal clean the second factor, to improve the performance of NTN bearing NSK bearing is adopted on Super - TF bearing steel. This material has solved under the condition of pollution or insufficient lubrication bearing life problems. Experience shows that under the condition of pollution operation, bearings are susceptible to debris intrusion and pollution. The company's research shows that on the edge of the pollution or lubrication bearing life can be improved under the condition of bearing steel microstructure and improve. The new seal structure is given priority to seal and hole sealing. Bearing of negative pressure can result in water from the main sealing intrusion, hole sealing structure has a great influence on the negative pressure. Therefore, reduce the negative pressure in the bearing is to prevent the water into the basic requirements. The most effective way is to make the hole sealing no direct contact with water, while retaining the original function - hole sealing — To prevent water and dirt intrusion from NTN side. Sealing methods for line contact surface contact, whether it's running process, or stationary process, surface contact hole sealing are characterized by the good sealing. Therefore, the new super seal clean NTN bearing capacity than the traditional sealed bearing has higher reliability.
