This series is screw driven, with fully enclosed, small, lightweight and high rigidity features. This stage contains a motor-driven balls crew module equipped with a stainless steel cover strip to prevent particles from entering or exiting.
The major differences between a rolled and ground ball screw are the manufacturing process, the lead error definition and geometrical tolerances. KGG rolled balls crews are made through a rolling process of the screw spindle instead of a grinding process. Rolled balls crews provide smooth movement and low friction which can be supplied quickly View from stock, at a lower production cost.
KGG precision ground balls crews are made through a grinding process of the screw spindle. Precision ground balls crews provide high positioning accuracy and repeatability, smooth movement and long service life. These highly efficient ball screws are a perfect solution for a variety of applications.
