Five ways to identify the quality of TIMKEN bearings

The quality of the TIMKEN bearing in use directly affects the working effect of the machine, so it is necessary to judge whether the quality of the bearing has reached the standard before use. Today, we will analyze the specific method of judgment.

Judging whether TIMKEN bearing outer package is clear

Under normal circumstances, the Zhengchang brand has its own specialized designer who designs the external packaging. After careful observation, it should be able to judge it and arrange production conditions to pass the production and production. Therefore, the packaging is very clear from the line to the color. Unambiguously. Some manufacturers also have some special identifiers, so pay attention.

Check the stencil printing is clear

In the TIMKEN bearing body will be printed with the brand words, labels and so on. Although the font size is very small, most of the products produced by the factory are stamped and printed without the heat treatment. Therefore, although the font is small, it is concave-deep and very clear. Counterfeit products have a very confusing font, because the printing technique is rough, the fonts float on the surface, and some can easily be wiped off with a damp cloth or hand.

Listen to TIMKEN bearing noise

Hold the TIMKEN bearing body in your hand, turn the jacket to rotate it, and listen for any noise. This is the biggest difference between the standard production TIMKEN bearings and the machine-operated OEM brands. The production conditions of most counterfeit products are backward, and manual workshop-type operations are completely carried out. In the production process, impurities such as sand are inevitably incorporated and hidden in the TIMKEN bearing body. Therefore, noises may occur when rotating.

Check for turbid oil stains, rust, corrosion

Imported TIMKEN bearings can hardly see traces of anti-rust oil. Since the current domestic anti-rust technology is not mature enough, it is easy to leave a thick trace of oil on the TIMKEN bearing body when it is subjected to anti-rust treatment. If you are familiar with it, smell the smell of TIMKEN bearings, you can also smell anti-rust oil, just Can't see it.

Finally, see if the chamfer is even, that is, the intersection of the horizontal plane and the vertical plane. Counterfeit TIMKEN bearings have no high-tech equipment because of the limitation of production technology, so they will be handled poorly in these corners and corners. It is easy to see.
