WV (DYNALINE®) Linear Units

Thomson's WV (DYNALINE®) positioning slides utilize a patented screw support technology. In addition, its patented plastic coverstrip system allows operation in dirty environments while keeping the internal system components fully protected. The WV Series differs from WM Series in that external guides are required.
