WM40 (POWERLINE) Linear Units

Thomson's WM40 (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.
