1. Whether the outer packaging of imported bearings can be clearly seen under normal circumstances; the imported bearings of the factory brand have their own special depictors to describe the external packaging; and the factories that produce the production conditions are manufactured and manufactured; therefore, the packaging is from line to color. Very clear; unambiguous, some imported brands have a special depiction on the packaging of their own personalities to protect their intellectual property.
2. Whether the steel printing on the imported bearings can be clearly printed on the imported bearing body will be printed with the brand typeface, label, etc. The font is very. Qin 銎 銎 銎 蠖 褂 褂 褂 〖 〖 酰 酰 酰 酰 酰 酰 酰 酰 谖淳 谖淳 棺 棺 棺 棺 棺 棺虼俗痔逅淙恍. The former 嫉 睿 环 环 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而 而
3. Whether the bearing body of the imported bearing has a strange noise, the left hand grasps the bearing inner sleeve of the imported bearing; the right hand pushes the outer sleeve to make it rotate; whether it can have a strange noise. Because the production conditions of some counterfeit products are backward; thorough craft workshop operation In the production process, it is inevitable to incorporate impurities such as sand; it is hidden in the bearing body; therefore, the noise will be announced during the rotation. This is the largest between the factory brands that strictly enforce the production specifications and operate with the machine. Different.
4. Whether the appearance of imported bearings can have dirty oil traces. This should be uniquely noticed when purchasing imported bearings. The unique and careful expert said that the imported bearings smelled like a smell; it must be rust-proof oil; just can't see it.
5. Whether the chamfer of the imported bearing can evenly chamfer the so-called imported bearing; that is, the intersection of the horizontal surface and the vertical surface; the counterfeit imported bearing is restrained by the production skill; the position at the corners of these edges is unsatisfactory.

Welded Steel Pipe, also known as welded pipe, is the use of steel or steel strip after the formation of welded steel pipe, the general length of 6 meters. Welded steel pipe production process is simple, high production efficiency, more varieties and specifications, less equipment investment, but the general strength below the seamless steel pipe.

Welded pipe  are widely used in boiler, automobile, ship, building doors and windows of light structure, furniture, all kinds of agricultural machinery, shack frame, threading pipe of electric wire, high level goods shelf and container, et
