Why big balls?
The load capacity of a ball screw increases with the ball diameter and the number of turns. The Hercules series utilizes the largest possible core diameter for each size increment. Combined with the optimized raceway, the load is distributed evenly across many balls, which increases service life and operational reliability.
Features
The heavy-duty nut is the ideal lead screw drive for heavy-duty applications such as presses and forming machines, injection molding machines, heavy-duty machine tools, and lifting equipment.
