Luoyang Huigong Bearing, always at the forefront of technology

The low-temperature friction torque of thin section angular contact ball bearings at -55°C increases abnormally. Tested two types of bearings, our company conducted detection and analysis of the friction torque at room temperature and low temperature. After detecting the starting friction torque, the bearing still cannot start normally after adding a 300g weight, and its friction torque is much greater than the requirement.

1. Reason for fatigue peeling failure 2. Wear and tear failure

Rolling bearings are precision mechanical parts. Whether they are installed correctly directly affects the accuracy, life and performance of the bearings. Therefore, the installation and removal of bearings must be carried out in the correct way and with appropriate tools.

Select the test environment: The test should be carried out in an anechoic chamber with good acoustic performance. The anechoic chamber can effectively absorb the incident sound waves, and the impact of the reflected sound waves on the sound field can be basically ignored, thus providing an environment close to the free sound field.
