The precision trapezoidal screw pair is a commonly used marine component in tool machinery and precision machinery. The main function of this part is to convert rotational motion into linear motion. At the same time, the precision trapezoidal screw pair has the characteristics of high precision, reversibility, and high efficiency. Because the friction coefficient of this part is small, the precision trapezoidal screw pair is widely used in various industrial equipment and precision instruments.

Precision trapezoidal screw pair has low friction loss and high transmission efficiency

Due to the rolling motion of many balls between the screw shaft and screw nut of the precision trapezoidal screw pair, high motion efficiency can be achieved. Compared with the past sliding screw pair, the driving torque reaches less than 1/3, which means that the power required to achieve the same motion result is 1/3 of using a sliding screw pair. It is very helpful in terms of power saving.

High precision trapezoidal screw pair

Precision trapezoidal screw pairs are generally produced continuously using the world's highest level of mechanical equipment, especially in the factory environment of grinding, assembly, and inspection processes, with strict control of temperature and humidity. Due to a sound quality management system, accuracy is fully guaranteed.

High speed feed and micro feed of precision trapezoidal screw pairs are possible

Due to the use of ball motion, the starting torque of the precision trapezoidal screw pair is extremely small, and there will be no crawling phenomenon like sliding motion, ensuring precise micro feed.

High axial stiffness of precision trapezoidal lead screw

Precision trapezoidal screw pairs can be preloaded, as preloading can cause the axial clearance to reach a negative value, resulting in higher rigidity (in practical applications such as mechanical devices, the repulsive force of the ball can enhance the rigidity of the screw core by applying pressure to the ball inside the precision trapezoidal screw pair).
