When used as a linear guide linear slide, linear slide due to friction way to rolling friction, not only to reduce the sliding friction coefficient guided 1/50, the gap between dynamic friction and static friction also becomes small. So when the bed running time, there will be no slip phenomenon can be achieved by positioning accuracy μm level. Design of the rail system, and strive to have the largest area of ??contact between the silver rail screw fixed element and a mobile element, which not only can increase the carrying capacity of the system, and the system can withstand the impact of intermittent cutting or cutting generated gravity, the force spread widely on the silver rail slide, expanding the area of ??affordability. To achieve this, the groove shape of the rail system has a diverse, representative of two ways, one is called Gothic (pointed arch), is a semi-circular shape extending egh20ca silver rails on the point of contact for vertex; the other is a circular arc shape, can also play the same role. No matter what kind of structure, only one purpose, and strive for more contact with the rail rolling ball radius (fixed components). Factors determining system performance characteristics are: how the rolling element contact with the rail, which is the crux of the problem. Silver rails on the slider on the silver rails, machinery supplied by Koyo Koyo Machinery Co., Ltd., Dongguan City.
