Our Planetary Roller Screw series represents a next-generation high-performance linear motion transmission solution, engineered to deliver extreme load capacity, exceptional precision, and unmatched durability for the most demanding industrial applications. As a superior alternative to traditional ball screws, our planetary roller screws utilize a unique planetary roller mechanism to convert rotary motion into linear motion, combining the high efficiency of rolling contact with the extreme load-bearing capacity of multiple contact points. We offer three specialized product lines to cover diverse operational needs: Standard Planetary Roller Screw, Recirculating Planetary Roller Screw, and Reverse Planetary Roller Screw, each tailored to unique performance and application requirements.
Core Product Features
Extreme Load-Bearing & Rigidity: The planetary roller design creates hundreds of simultaneous contact points, delivering 5–10 times higher axial load capacity than equivalent ball screws, with exceptional rigidity to withstand heavy shock loads and high static/dynamic forces.
Ultra-High Efficiency & Low Friction: Rolling contact between the screw shaft, planetary rollers, and nut achieves up to 90%+ mechanical efficiency, drastically reducing driving torque, energy consumption, and wear compared to lead screws, enabling smooth, high-speed operation.
Superior Precision & Long Service Life: Precision-machined components and optimized roller circulation ensure minimal backlash, outstanding positioning accuracy, and exceptional repeatability, with a service life far exceeding traditional ball screws in high-cycle, high-load applications.
Three Specialized Product Lines:
Standard Planetary Roller Screw: The core general-purpose series, ideal for high-load, high-precision linear motion in industrial machinery, balancing performance, reliability, and cost-effectiveness.
Recirculating Planetary Roller Screw: Features a recirculating roller design for extended stroke lengths and continuous high-speed operation, perfect for long-travel automation and high-throughput production lines.
Reverse Planetary Roller Screw: A compact, high-thrust solution with a rotating nut and fixed screw design, enabling space-saving integration and high-speed linear actuation in limited-installation-space applications.
High-Speed & High-Acceleration Capability: Optimized roller dynamics enable exceptional rotational speeds and acceleration rates, making them ideal for dynamic motion systems requiring fast, precise positioning.
Robust Design for Harsh Environments: Manufactured from high-hardness, wear-resistant alloy steel with advanced heat treatment and multi-layer sealing systems, ensuring reliable operation in dusty, high-temperature, and heavy-duty industrial environments.
