Description

Technical Field

[0001] The utility model relates to a bearing test device, in particular to a compression durability test device for the bearing of an automobile shock absorber assembly. Background Art

[0002] A bearing is an important component used for the rotational support of a mechanical body. Bearings have a very wide range of uses. In order to adapt to various application scenarios, there are also many types of bearings. Among them, the bearing of an automobile shock absorber assembly is a type of bearing used on an automobile shock absorber assembly. This type of bearing is arranged between the spring and the upper end of the automobile shock absorber assembly, mainly to form a movable connection between the vehicle body and the assembly, avoiding direct friction. It is very important. If it fails, it often causes relatively large losses. Therefore, before leaving the factory, it is often necessary to test the durability and life of this type of bearing under the compressed state to provide customers with a more safe and reliable shock absorber assembly bearing.
