Injection molding and metal fabrication machines, where ball screws can handle high loads in a short stroke with high precision.Large fabrication equipment, including mills, water jets, plasma cutters and automatic welders, which must control motion on horizontal and vertical axes.They minimize replacement and maintenance costs significantly for the application, which provides an ideal opportunity to replace roller screws or hydraulic systems in applications with axes that require accurate and safe movement of heavy loads, long and reliable life, and minimum maintenance. High-load ball screws are ideal for demanding motion control applications such as injection molding, pressing, and large fabrication equipment. Made for the Most Demanding Industrial Applications A roller screw is also capable but has a nut that is close to 50% larger and would cost 150% the price of the comparable high-load ball screw. A standard configuration ball screw can provide a solution but would have twice the diameter and cost 63% more. The table below illustrates the advantage of a high-load ball screw in an application that requires a minimum of 470 kN of load capacity. Thomson high-load ball screws provide maximum load capacity and longer life in a compact envelope! Available with up to 15 m screw length and with single or double nuts.Optimized ball nut design for maximizing load capacity.Compact, simple design allows for downsizing, less weight.Increased capacity for high-load applications at high speeds and long lifetimes.They provide smooth, quiet motion at higher speeds over a longer life. Preloading options are available upon request, and Thomson will customize the ball screw to meet customer-specific applications. They come in standard sizes up to 160 mm in diameter with up to 1,440 kN of dynamic load capacity. They are available with up to 15 m screw lengths and with single or double nuts.

Thomson high-load ball screws can handle more than double the load capacity or provide 10x the service life when compared to standard ball screws at equivalent performance points.
