Trapezoidal Threaded Rod

Trapezoidal threaded rod is a kind of rod-like parts with trapezoidal threads. Its thread profile is trapezoidal, and this shape gives the thread good load carrying capacity and transmission efficiency when subjected to axial force and torque. Trapezoidal threads have a relatively large pitch, and compared with other threads, trapezoidal threads are capable of transmitting greater axial forces at the same nominal diameter. Trapezoidal threaded rods are mainly used for mechanical transmission and connection. In the transmission process, by rotating the threaded rod, the spiral rise angle of the thread is used to convert the rotary motion into linear motion, or through the cooperation with the nut to realize the axial fastening and displacement adjustment.

In the field of machine tools, trapezoidal threaded rod is a key component of the machine tool feeding system. For example, in lathes, milling machines and other machine tools, it is used as a screw to convert the rotary motion of the motor into the linear feed motion of the tool or table, and precisely control the machining accuracy. In lifting equipment, such as jacks, electric hoist lifting mechanism, the trapezoidal threaded rod bears the gravity of the heavy object, through the rotation of the heavy object will be raised or lowered smoothly.
