Description
This Helical Gear Rack is composed of screw, nut, steel ball, prepress plate, inverter and dustproof device. It is an ideal product for converting rotary motion into linear motion or linear motion into rotary motion. The device is the most commonly used transmission element in tool machinery and precision machinery. Its main function is to convert the rotary motion into linear motion, or to convert the torque into the axial repeated force. Our Helical Gear Rack has the characteristics of high precision, reversibility and high efficiency. It is widely used in a variety of industrial equipment and precision instruments.
