Ball Screws and Nuts

Ball screws offer a highly efficient means of converting rotary motion to linear motion. Precision ball screws have several bearing balls that transfer the load between the nut and screw. Ball Screws and Nuts are high performance linear drive systems. Ideal for industrial and automation applications in general, they are used in the most varied application sectors, such as machine tools and industrial machines, injection molding machines, presses, automatic production and assembly lines, assembly devices for electronic components, medical equipment and precision instruments. They can be used as positioning screws, integrated in systems which require great stiffness, high positioning accuracy and repeatability. Another use is as transport screws where they are used to move a specific load without particular positioning requirements. In addition to the vast production program available in the catalog, Servomech is also able to create customized products based on the customer's specific application needs.
