Zimm | Z-Series | Ball Screw

The ball screw is used primarily when higher positioning and repetition movements are the priority.

The ball screw's efficient threaded nut design enables higher operation cycles, duty cycles, and speeds due to its superior efficiency over trapezoidal threads. This results in lower energy consumption and reduced heat generation from smoother movements. Ball screws can achieve up to four times the operation cycles of trapezoidal threads and are available in various pitches for different lifting speeds.
