background

The bearing is one of the key parts in mechanical equipment, and the operating state and the use performance of the equipment are directly influenced by the quality of the operating state of the bearing. However, the working conditions of the bearings are generally very severe and complex, the bearings often work under the working conditions of high speed, high temperature and high load, the working conditions change violently during the work, and the bearings are very easy to have faults of abrasion, fatigue peeling and the like during the work. Once the bearing fails, the use safety of the equipment is directly affected, and even catastrophic accidents can be caused in severe cases.
