NTN deep groove ball bearings with the performance demands of sealing material

NTN bearing use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. According to the deep groove ball bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjust, make its restore normal function of deep groove ball bearing seal materials is the first element of effective sealing, choose sealing material, if according to the performance of the sealing element, such as using temperature, working pressure, working medium and used by movement postures pattern, etc. The basic request of sealing material is as follows: 1. NTN bearing wear resistance, erosion of metal; 2. Oxygen resistance and aging resistance, durable; 3. Not bearing high soft low temperature resistance, high temperature synthesis, softening, low temperature not hardening; 4. NTN bearing to adapt themselves to the working medium, no swelling, synthesis, hardening, etc. ; 5. Squeeze for deformation small, well elasticity and hardness; NTN bearing materials of metallurgical quality was the main factor affecting the premature failure of the deep groove ball bearings. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered.
