The thread of the trapezoidal screw usually adopts the trapezoidal thread shape, and the common types include triangular thread, rectangular thread and tapered thread. Threads are characterized by parallel helixes that convert rotational torque into linear motion by rotating the screw. The nut is the part that engages with the thread of the screw, and it is fixed on the component that needs linear motion.

1. High precision: The design and manufacturing precision of the linear guide is very high, which can provide extremely high positioning accuracy and repeatability. 2. High rigidity: Linear guide rails have high rigidity, can withstand large loads and torques, and maintain the stability of the mechanical system. 3. Low friction: Due to the use of balls or rollers between the guide rail and the slider, the friction is low, which can provide smooth movement and high efficiency. 4. Long life: The material and manufacturing process of the linear guide ensure its long service life and wear resistance. 5. Quick installation: Linear guide rails usually have a modular design and can be quickly installed into various mechanical systems.

A linear guide is a precision guide used in mechanical systems to provide smooth and accurate linear motion. It usually consists of two parts: rails and sliders. A rail is a straight metal strip or profile with special grooves or protrusions that guide the movement of the slider. Sliders are moving parts mounted on rails, usually made of metal, containing balls or rollers inside to reduce sliding friction and provide high-precision linear guidance. Ship
