Technical Field

[0001] The utility model relates to the technical field of anti-loosening testing machines, in particular to an anti-loosening testing machine for a bearing with a seat. Background Art

[0002] The seated bearing anti-loosening test is a method used to verify the tightness of the connection between the bearing and the seat. During the test, the bearing is first secured to the seat, and then a force or vibration is applied to simulate the forces or vibrations that the bearing may experience during operation. By observing whether there is any looseness or displacement between the bearing and the seat, the tightness of the connection can be determined, ensuring that the equipment will operate without problems.
