You big profit bearing, have you found?

The most common, the most commonly used bearing, with guide rail, first say bearing, bearing is a kind of important modern machinery and equipment parts. Its main purpose is to support the mechanical rotator, reduce the coefficient of friction in the process of the movement, and guarantee its rotary precision ball bearing bearing bear with the shortage in the mechanical parts, so its dosage is very big, so have many manufacture to do it, the middlemen to resell, bearing is good many, of course, here I am not a good explanation, and will give you look at the price of the most common bearing with middle of profits: buy price sell the price will be able to see from the picture, the price of the most common bearing, by middlemen sell the price is nearly 180%, the dosage of the bearing is also able to see from the picture, this is the profit in the middle of such fear down to tell everyone about guide rail, so what is the guide? Many people may not know? Guide rail tank made of metal or other material or ridge, acceptable, fixed or move installation guide or an installation of equipment and reduce the friction. Guide rail longitudinal slots in appearance or ridge, used to guide, fixed special machine parts, equipment, instruments, etc. Guide is also called the slide rail, linear guide, linear slide rail, used for straight line reciprocating movement, has higher than linear bearing load rating, able to bear certain torque at the same time, it can be finished under the condition of high load and high precision linear motion. Guide general speaking, sliding plastic guide rail is the most distinct features of the excellent rigidity, vibration absorption ( To suppress vibration of tool cutting) And damping ( Avoid start or stop the vibration of the rail system) Large machine tool use, suitable for cutting load. The price is also turned over more than 110%, a few layers of middlemen markups, finally to the buyer, can measure more than 260%, buyers bear the price rising machine price, product price rising, there are a few things middlemen fire in the middle price, but we don't know.
