Bearing is a component that fixes and reduces the coefficient of friction of the load during mechanical transmission. It can also be said that when other mechanisms are relatively moved relative to each other on the shaft, the mechanism for reducing the coefficient of friction during power transmission and maintaining the center position of the shaft is fixed.
1. Look at the FAG imported bearing logo. Some of the components on the track are marked with some marks, such as the top mark of the gear mark, etc., to ensure that the machine is correctly installed, and no one can not be purchased.
2, look at the FAG bearing color. Some original parts are assigned a certain color, and in the case of other colors, they are fake parts.
3. Look at the surface of the FAG bearing. The original parts are printed on the surface or the letters and signs are clearly on the right track, while the impersonation products have a rough appearance.
4. Look at the paint. Unscrupulous traders can easily dispose of used parts, such as dismantling, loading, splicing, scraping, painting, etc., and then pretend to sell qualified products, and illegally obtain high profits.
5, look at FAG imported bearing texture. The information of the original parts is qualified according to the design request, and the products are mostly cheap and inferior materials.
6, look at the missing. The components of the orbital assembly must be completely defective to ensure smooth installation and proper operation. A small number of small parts on the assembly are missing, which makes the device difficult to form. Often due to the adequacy of small accessories, all assembly parts are scrapped.
7. Look at FAG imported bearing storage. If the auto parts show an issue such as cracking, oxidation, discoloration or aging, it can be formed during the storage period due to poor environment, long storage time, and poor data.
8, look at FAG imported bearing joints. If the clutch plate rivet is loose, the brake pipe is degummed, the electrical parts are unsealed, and the paper filter joint is disconnected, it cannot be used.
9, look at FAG bearing packaging. The original parts are packaged with common standard, consistent specifications, and the printed words are clearly on the right track. The fake product packaging is more delicate and can easily find the loopholes from the packaging.
10, look at FAG imported bearing technology. Inferior products sometimes have a good appearance, but due to poor manufacturing processes, cracks, sand holes, slag inclusions, burrs or bumps are easily displayed. The cylinder head is squeezed and deformed, which easily causes the seal to be ablated and ablated, causing oil leakage, air leakage and water leakage; the piston and piston ring task have burrs and easy to pull the cylinder.

CNG Pressure Gauge
CNG pressure gauge(sensor) is used to measure the pressure of CNG inside the gas cylinders of the CNG vehicle. It coverts the pressure into the electric signals and sends the electric signals to the driving cab so as to observe the pressure of the gas cylinders.
