High-Load Ball Screws

Thomson high-load ball screws are ideal for large fabrication machines in injection molding, pressing and metal fabrication. They move heavy loads in horizontal and vertical axes accurately and safely, while providing long and reliable life with minimum maintenance. Our standard portfolio contains sizes up to 160 millimeters in diameter with a maximum dynamic load of up to 1,440 kN. Thomson also has the capability to customize these ball screws according to your specific application requirements.
