How to distinguish true and false bearings?

Bearing is an important part of mechanical equipment.Its main function is to support the mechanical rotating body, reduce the friction coefficient in the process of movement, and ensure the accuracy of rotation.

In the production and processing, once the fake and inferior bearings are used, the consequences are not only to lead to machine maintenance and even shutdown, but also to create millions of losses for the company.

At present, the plain bearing counterfeits are rampant. The self-lubricating bearing suppliers have turned to malicious competition, slandering each other, competing to lower the sales price, and repeatedly challenging the bottom line of bearing quality. Today we teach you how to distinguish fake bearings!

• First, believe that cheap not good goods

The market is mixed, counterfeit bearings are very difficult to identify.These shoddy products may not have scratches, rust or stains and may not be cheaper than the real thing.However, you should be on the lookout for these “attractively priced” bearings.If they are priced well below the market price and are in large supply, there are probably some reasons not to let the illegal trade destroy your project.

• Second, choose the brand with high credibility

Understanding the domestic and foreign bearing brands and their product specifications can effectively avoid the purchase of inferior bearings. Choosing a trustworthy big brand can enjoy better quality assurance and after-sales service. Viiplus is the world high quality in self-lubricating bearings solutions. With many years of history, we have accumulated a lot of experience and high quality products, which are worthy of your trust.

• Third, choose a reliable channel to buy

You can purchase directly from the manufacturer or through the manufacturer’s authorized dealer/agency.

• Forth, Careful inspection and inspection

1. Check whether the outer packing of bearings is clear

2. Understand the bearing manufacturer in the corresponding bearing typing specifications: bearing model, trademark, year, etc

3. Observe whether the brand words/marks on the bearing body are clear

4. Observe whether there is oil mark or noise on the surface

5 method to identify the true and false of plain bearing.

1. Is the steel printing of plain bearing clear?

Each carrier product will have its own brand, label, etc. Printed on the body of the carrier product. Although the font is tiny, the products produced by regular manufacturers are stamped with steel stamping technology and pressed before being heat treated. Therefore, although the character is small, it is deep and palpable. In general, the fonts of counterfeit products are not only blurry, but due to the rough printing technology, the fonts float on the surface and some can even be easily erased by hand or have severe hand marks.

2. Bearing whether there is noise

Hold the bearing inner sleeve with your left hand and gently rotate the outer cover with your right hand to make it turn. Listen to the noise while the bearing is in operation. Due to the backward production conditions of most of the counterfeit products and the fully manual workshop operation, impurities such as dust and sand are inevitably mixed into the bearing body during the production process, resulting in noise or uneven maintenance as the bearing rotates.

This is the key to judging whether the product is from a branded product from a regular manufacturer that has strict manufacturing standards and is run by a machine.

3.Whether there is muddy oil on the surface

If there are muddy oil marks on the surface, we must pay special attention when purchasing imported plain bearings. As there is still a particular gap between domestic anti-rust technology and foreign countries of advanced manufacture, it is easy to leave thick oil marks when the anti-rust treatment is carried out on the plain bearing body. It looks sticky and opaque when touched by hand and the foreign original. There are almost no traces of antirust oil in the imported plain bearings. According to industry insiders, cautious people can smell the characteristic smell of imported plain bearings, which is the smell of anti-corrosion oil.
