What cause the damage of sliding steel sleeve ?

Steel sleeves are regular units in machine,MarginalBearing tells the causes of the damages of them.

1. If the coating machine bearing parts in the processing process and the finished coating machine bearing finished products are not subjected to rust treatment in strict accordance with the requirements of cleaning and anti-rust regulations and oil seal anti-rust packaging during the production of coating machine bearings. For example, the turnaround time of the ferrule is too long, and the outer circle of the outer ring is in contact with corrosive liquid or gas.

2. The quality of the products such as anti-rust lubricating oil and kerosene used in the production can not meet the requirements of the process technology and cause damage to the copper sleeve.

3. The turning allowance and grinding allowance of the steel sleeve of the coating machine are too small, and it is also one of the reasons that the scale and decarburization layer on the outer circle cannot be completely removed.

4. If the content of harmful substances in the air is high, the production environment is relatively poor, and it is difficult to carry out effective anti-rust treatment. In addition, the weather is hot, or production workers violate the rust prevention regulations, and so on.


5. The anti-rust paper, nylon paper (bag) and plastic tube and other coating machine steel sleeve packaging materials do not meet the requirements of the anti-rust packaging of the roller coating machine bearing oil seal is also one of the factors causing rust.


6. As the price of the bearing steel of the coating machine drops, the material of the bearing steel of the coating machine gradually declines. For example, the content of non-metallic impurities in steel is relatively high (the increase of sulfur content in steel makes the material's own anti-corrosion performance decrease), and the metallurgical structure deviation.


The main function of the steel sleeve is to support the mechanical rotating body, reduce the friction coefficient during the movement, and at the same time ensure its rotation accuracy.


According to the survey, poor lubrication is one of the main causes of premature damage to the steel sleeve. 50% of the premature damage is caused by poor lubrication, specifically including: failure to refill lubricating products in time, lubricating products The type selection is wrong or not filled in place, the lubrication method is incorrect, etc.


Before lubricating the steel sleeve, be sure to select the correct lubrication product and fill it in the correct way.
