It is not only a four-legged wheel that requires the use of bearings; it is indispensable for all the machine parts that will change; it is a very inconspicuous in the transmission system. Contact serious things. Because of the large amount of work; its wear is also relatively high; so replacing the bearing is a common job in car repair. Walking in the auto parts market.

Whether the outer packaging can be clear: Under normal circumstances; the factory brand has a special depiction of the external packaging; and the factory that produces the production conditions is manufactured; therefore, the packaging is very clear from line to color; Vague. (Some imported brands have a common depiction on the packaging of their own personalities to protect their intellectual property; this will be continuously analyzed in the future).
Can the steel printing be clear: the brand name, label, etc. will be printed on the bearing body. The font is very. Qin 銎 銎 銎 褂 褂 褂 褂 〖 〖 酰 酰 酰 〖 谖淳 谖淳 碇熬 碇熬 碇熬 碇熬 碇熬 碇熬 碇熬 棺 棺 棺 棺 棺 棺 棺 棺 棺 棺 棺嫉. The front 嫉 睿 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

Whether the chamfer can be even: the chamfer of the bearing; that is, the intersection of the horizontal and the vertical; the counterfeit bearing is restrained by the production skill; the position of the corners is not satisfactory.
