WM (POWERLine) Linear Units

WM (POWERLine) Ball Screw Unit, Ball Guided

Thomson's WM (POWERLine) positioning slide utilizes a patented screw support technology. In addition, its patented plastic coverstrip system allows operation in dirty environments keeping the internal system components fully protected while reducing friction to a minimum. The WM40 model of this family is specifically designed for miniaturized applications with extremely small dimensions.
