Screws

Metric Rolled Ball Screw Assemblies are designed to provide quiet, smooth running, efficient performance.  Ball screws are manufactured using Thomson’s patented, German-engineered Precision Screw Forming (PSF) Technology, which provides high accuracy (±23µm/300mm standard) with the manufacturing efficiency of rolled processes. Ball nuts are manufactured with one of three ball return systems (depending on the diameter and lead of the screw) made with reinforced steel, making them extremely durable and ideal for high speed, high load, and/or high temperature applications. Ball nuts come standard with profiled wipers to contain lubricant and help repel fine contaminants (dust, powder, etc.).

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.
