轨道车辆轮对滚动轴承橡胶密封装置性能试验
Application Summary AI generated
This standard specifies the test methods for evaluating the performance of rubber sealing devices used in rolling bearings for railway vehicle wheelsets. It is applied in the manufacturing and quality inspection of rubber seals for high-speed trains, metro cars, and freight locomotives to ensure sealing integrity against contaminants and lubricant leakage under dynamic operating conditions. The standard is used by bearing manufacturers, railway maintenance departments, and testing laboratories to validate seal durability, friction torque, and temperature resistance.
