Identify the counterfeit bearings on the explosion-proof vibration motor!
Explosion-proof vibration motors are widely used in the vibrating screen industry. The performance of vibrating motors is relatively high, which can solve the problems in vibration machinery operation. Due to its special structural principle, the advantages and disadvantages of using bearings directly determine the quality of the rapping motor and the length of its service life. Of course, it will also be reflected in the price level of the explosion-proof vibration motor. Therefore, the manufacturer of regular bearings is a must, how to identify counterfeit bearings can learn from the following methods:
1, look at the packaging
The packaging of regular original bearings is generally more standardized, divided into inner packaging and outer packaging, the standard is standardized and the writing is clear, while the counterfeit product packaging is generally inferior in material and rough in printing.
2, look at the color
The specific part of the original bearing has a certain fixed color, for example: the chamfer is black. In case of other colors, it may be a fake bearing. There is also a bearing finish, which is basically a fake below (△8).
3, look at the appearance
The original bearing letters are engraved or sprayed, the fonts have a special design, and the counterfeit products are printed in a fuzzy manner.
4, see the material
The material of the original bearing is selected to meet the standard bearing steel material, and the counterfeit products are mostly cheap and inferior materials, which are used to reduce the manufacturing cost and light weight.
5, see the process
The original bearing manufacturing process is fine and the sliding property is good. The manufacturing process of the counterfeit bearing is poor, the surface is rough, the cage is easily deformed, and the operation is not smooth.
6, look at the price
The price of the original bearing is relatively transparent, and there will not be much difference in the price of each place. If the purchase price is too cheap, you need to be vigilant, prevent greed and eat big losses, and cause unnecessary losses.
