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.

The WM family has a unique feature of an internal movable ball screw support, which allows for long lengths and high speeds. The WM Units are ideal where stiffness, rigidity, and/or precision may be required - such as machine tool automation or test and measure. Thomson can provide units up to 11 meters in length...
