Questions more>>

  • Ask：What is a trapezoidal screw? Characteristics and Requirements of Trapezoidal Screw Rod

    answer:Trapezoidal screw belongs to a type of spiral transmission. By transmitting motion and power through the rotation of nuts and screws, rotational motion can be transformed into linear motion. The trapezoidal screw has the characteristics of high transmission efficiency, accurate positioning, and high load-bearing capacity.

  • Ask：What is the difference between trapezoidal screw and ball screw?

    answer:The motion principle of trapezoidal screw and ball screw is the same, the difference is that there are no balls in trapezoidal screw, so the motion between the nut and the screw shaft is completely generated by mechanical contact to produce sliding. So the main difference between the two structures can be summarized in one sentence: ball screws are rolling friction, while trapezoidal screws are sliding friction.
