Thread rolling screw

Thread rolling screw

High-speed and space-saving linear motion! A screw that converts the rotational motion of a motor into linear motion.

The "transformed sliding screw" is a functional screw that converts the rotational motion of a motor into linear motion through a screw. The amount of movement per rotation is 45mm, providing high-speed performance. By reducing the contact area, it achieves high efficiency through excellent sliding properties. The resin nut uses a special resin that excels in sliding properties, heat resistance, and water absorption, allowing for low noise and lighter sliding with lower torque compared to trapezoidal screws. 【Features】 ■ Achieves high-speed linear motion and space-saving design ■ Maximum lead of 45mm ■ High efficiency through excellent sliding properties ■ The resin nut uses a special resin with added solid lubricants *For more details, please refer to the PDF document or feel free to contact us.

Rolling screw

Rolling screw

A material that excels in sliding properties, heat resistance, and water absorption compared to polypropylene, nylon, and polyacetal.

The "sliding screw" is a screw that achieves high-speed linear motion and space-saving design. The resin nut is made from PPS as the base material, and a special resin with added solid lubricants (such as fluororesin) is used to improve sliding characteristics. Compared to polypropylene, nylon, and polyacetal, it is made from a material that excels in sliding performance, heat resistance, and water absorption, operates with lower noise compared to ball screws, and slides more lightly with lower torque than trapezoidal screws. 【Features】 ■ High efficiency achieved through excellent sliding properties ■ The resin nut is based on PPS ■ A special resin with added solid lubricants (such as fluororesin) is used to enhance sliding characteristics ■ Lower noise compared to ball screws ■ Slides more lightly with lower torque than trapezoidal screws *For more details, please refer to the PDF document or feel free to contact us.
