Product Description

Product Description

 

Precision Screw Pair

As a typical screw transmission, screw pair has the characteristics of mutual conversion between rotational motion and linear motion. According to the circulation mode, it is divided into internal circulation screw pair and external circulation screw pair. Internal circulation screw pair refers to a screw pair in which the ball never leaves the surface of the screw during the circulation process, and has the characteristics of compact structure, less friction loss, high transmission efficiency, good rigidity, etc.; external circulation screw pair refers to a screw pair in which the ball leaves the surface of the screw when the circulation is reversed, and has the characteristics of simple structure, good processability, and reliable operation.

Ball screw transmission is to place a proper amount of balls as intermediate transmission bodies between the screw and the screw nut spiral groove, and use the return device to make the balls form a spiral motion chain that circulates repeatedly in the closed loop. The relative motion of the screw and the nut is transformed into rolling contact by the action of the ball chain. 

The ball screw pairs manufactured by our company have been serialized and standardized. We have built a ball screw pair design, manufacturing, assembly, and testing center with an annual production capacity of 50,000 sets, and can provide users with high-quality and efficient services.

LINEAR MOTION

Trapezoidal screws pair are often used in linear motion systems, such as CNC machines, 3D printers, and Cartesian robots. In these applications, the screws convert rotational motion from a motor into linear motion to precisely position and move components, tools, or print heads along linear guides. The linear positioning achieved by trapezoidal screws is essential for accuracy, repeatability, and control in manufacturing, fabrication, and automation tasks.

ACTUATORS

Trapezoidal lead screws pair are commonly used in conjunction with nuts to form linear actuators. These actuators provide controlled linear motion for applications such as robotics joints, automated assembly, material handling, and precision positioning of sensors, cameras, and instruments. Trapezoidal lead screw actuators are often selected for their ability to provide reliable motion with minimal backlash and play.

MEDICAL DEVICES

Trapezoidal screws pair are employed in various medical devices and equipment that require precise positioning and motion control. Examples include infusion pumps, robotic surgical systems, imaging devices (such as MRI and CT scanners), and patient-handling equipment. The accuracy and repeatability of trapezoidal screws contribute to the reliable operation and safety of these critical medical systems.

AUTOMOTIVE APPLICATIONS


Trapezoidal screws pair are used in various automotive applications where linear motion and positioning are required. Examples include power window mechanisms, seat adjusters, sliding door mechanisms, and automatic trunk/liftgate mechanisms. The durability and efficiency of trapezoidal screws make them suitable for automotive systems that demand both performance and comfort features.

DIAMETER


Precision Trapezoidal Screw Pair comes in different diameters per the task. The diameter impacts the torque, load capacity, and overall functionality. For example, a larger diameter screw will handle greater loads and generate more torque compared to smaller ones.
