China Linear Guide Way 35mm SER-GD35WA HGW35CC with High Precision

china manufacture china linear guide way SER-GD linear guide rail ,guide blocks and guide sliders

A. STRUCTURE CHARACTERIISTICS 
  Linear rolling guide consists of slider, guide rail, rolling element(ball or roller), reverser, holder and end seal, when the guide rail and the slider move relatively, the rolling element(ball or roller), in four raceways(circular or plane)which are 45 degree angle of contact and in symmetrical arrangement, make infinite loop movement through raceways(circular or plane) and reverser at both ends of the slider, to achieve linear motion. End seal device at both ends of the slider, could effectively prevent and take away the dust, oil, iron, and other debris, and prevent them from coming into the internal of the slider, therefore it has ensured accuracy and service life of the guide pair. 
B. Advantages.
         Linear rolling guide, changes the sliding friction into rolling friction by putting appropriate rolling element(ball or roller) between the guide rail and the slide raceway(circular or plane), as a result, the friction resistance decreases more than fifty times. It has minimal movement friction resistance, and has greatly improved the mechanical efficiency and won motion accuracy and positioning accuracy of um level. 
1)  Dynamic and static friction resistance difference is small, which is helipful to improve the response speed and sensitivity of CNC system.
2) The driving power is small, which reduces the energy consumption.
3) High positioning accuracy and high repeat positioning accuracy.
4) by increasing preload, the rigidity is greatly increased.
Using Paired guide rails, it has the effect of homogenizing error. 
5) Can withstand the load from up and down or so.
6) The end and side of the slider can be manually or automatically lubricated oil cup.
7) It has simplified the design and manufacture of mechanical structure, therefore reduced the manufacturing cost.
