Ten tips to distinguish the authenticity of high temperature bearing

1. Look at the mark of high temperature bearing

Some regular parts are marked with some marks, such as the gear mark, the top mark and other assembly marks, which are used to ensure the correct installation of the machine parts. Those that are not available can not be purchased.

2. Look at the color of high temperature bearing

The surface of some original accessories is specified with a certain color. If other colors are encountered, they are counterfeit parts.

3. Look at the appearance of high temperature bearing

The original accessories have clear and regular printing or casting words and marks, while the appearance of counterfeit products is rough.

4. Look at the paint

Illegal businessmen will waste parts through simple processing, such as dismantling, assembling, assembling, assembling, painting and other treatment, and then pass off as qualified products to sell, illegally obtain high profits.

5. Look at the high temperature bearing texture. The materials of the original accessories are qualified materials according to the design requirements, and most of the counterfeit products are replaced by cheap and inferior materials.
6. Look at the gaps

Normal assembly parts must be complete and intact to ensure smooth installation and normal operation. Some small parts on some assembly parts are missing, which is usually "parallel goods", which makes installation difficult. Due to the shortage of some small parts, the whole assembly parts are scrapped.
7. Storage of high temperature bearing

The packaging of the original accessories is generally more standardized, unified standard specifications, clear and regular handwriting, while the packaging and printing of counterfeit products are relatively poor, so it is often easy to find defects in the packaging.
10. Look at high temperature bearing technology

Although the appearance of inferior products is good sometimes, it is easy to crack, sand hole, slag inclusion, burr or bruise due to poor manufacturing technology. Cylinder gasket extrusion deformation, easy to cause the seal is not tight and ablation, resulting in oil leakage, air leakage and water leakage; The working surface of piston and piston ring has burr, which is easy to pull cylinder.
