There are four main reasons for bearing chamber wear:

1. The reason for the size is mainly due to the error during machining: most of the bearing chamber and the bearing outer ring are generally made of a base shaft, and the usual fit is a small clearance fit or transition fit. Once the mating clearance is too large, the outer ring of the bearing will rotate at a high frequency in the bearing chamber, resulting in wear of the bearing chamber.

2. Normal metal fatigue wear: The metal itself has certain fatigue characteristics. Long-term vibration resistance will lead to normal fatigue wear of the metal. This phenomenon is determined by the characteristics of the metal itself. Therefore, only the metal production cycle is prolonged by improving the production process during the shaft production process. , to improve the service life.

3, the quality of lubricants: the commonly used lubricants are divided into synthetic oil and petroleum-based lubricants. Lubricating oil has certain anti-wear, pressure resistance and viscosity temperature. Therefore, inferior lubricants generally cannot be adapted to the high temperature environment in which the dryer is operated, resulting in cracking of the lubricating oil film or failure to form an effective lubricating oil film, resulting in poor lubrication of the bearing operation. Therefore, the friction coefficient is large during the operation of the bearing, which causes a large torque force to be formed between the inner and outer rings and the surface of the bearing chamber, resulting in wear of the bearing chamber.

4. Improper maintenance: Failure to replace bearings or poor lubrication is one of the main causes of bearing chamber wear.
