Product Description

Planetary roller screws are high-end core components for linear motion, widely recognised as one of the most reliable drive components in modern precision automation systems. Compared with conventional ball screws, they feature a unique multi-contact rolling structure, in which multiple rollers engage with the screw shaft and nut simultaneously. This design significantly enhances axial load capacity, torsional rigidity, positioning accuracy and service life, making them ideal for working conditions requiring heavy loads, high speeds, high precision and long-term stable operation. Boasting excellent characteristics such as a low coefficient of friction, high transmission efficiency, strong impact resistance, minimal backlash and ultra-high repeat positioning accuracy, planetary roller screws effectively improve the stability, response speed and control accuracy of mechanical systems. They are widely used in semiconductor manufacturing equipment, new energy equipment, precision testing instruments, industrial automation production lines, CNC machine tools, medical devices, aerospace systems and humanoid robots. Our company specialises in the R&D and production of high-performance planetary roller screws, offering customised design options regarding size, stroke, load capacity, accuracy grade and installation method. We are committed to providing customers with reliable, high-efficiency and long-life transmission solutions to meet the stringent requirements of advanced manufacturing for precision transmission components.
