High-speed ground Ball Screw

CHARACTERISTICS AND USE
The series of high-speed ball screws is characterised by a preloaded nut unit and double-loaded thread with high rise up to called "squire version" when the thred pitch P equals in nominaldiameter d0. The ball transmission method used allows for the movement speed up to 100m. min-1 to be reached. Reduced built-in lengths of the preloaded nut allow higher strokes to be reached at individual ades of working machines and consequent increase of the operation space of the machine. Thread lengths up to 2000mm.
