SFU Ball Screw
SFU ball screws are core transmission components used in CNC machines and automation systems to convert rotary motion into precise linear movement. Compared with traditional trapezoidal screws or sliding transmission mechanisms, SFU ball screws provide higher transmission efficiency, lower driving torque, smoother operation, and more stable positioning performance for precision motion control applications.
Product Introduction
Our SFU ball screw is designed to deliver high-efficiency and precise linear transmission for CNC machines and automation systems. Manufactured with precision-ground screw shafts, ball nuts, and circulating steel balls, it ensures smooth motion conversion from rotary drive to accurate linear movement. Compared with traditional sliding screws, the rolling ball structure significantly reduces friction, resulting in lower driving torque, improved energy efficiency, and stable operation. With optional C5 and C7 accuracy grades and preloading design, SFU ball screws provide excellent positioning accuracy, high axial rigidity, and long service life. Available in a wide range of models and customizable according to drawings, SFU ball screws are well suited for various precision motion control applications. We welcome customers to contact us for model selection and technical support.

Product Features
High efficiency
SFU ball screws use rolling steel balls between the screw shaft and nut to transmit motion, greatly reducing friction during operation and achieving high transmission efficiency with lower energy consumption.
Long service life
With precision-machined screw shafts, hardened steel balls, and smooth raceway surfaces, SFU ball screws offer excellent durability and stable performance over long-term continuous operation.
High rigidity and load capacity
The preloading design effectively eliminates axial clearance, enhancing axial rigidity and enabling the ball screw to withstand higher loads while maintaining stable motion control.
High precision
Available in C5 and C7 accuracy grades, SFU ball screws provide precise positioning, excellent repeatability, and reliable micro-feed control for CNC machines and automation systems.
Smooth and stable operation
The rolling contact structure minimizes vibration and crawling, ensuring smooth start-up, stable motion, and consistent performance even at low speeds.
Product Application
Precision motion control systems are widely used in modern manufacturing and automation equipment, where accurate positioning, smooth movement, and high efficiency are essential. As industrial technology continues to advance, demand for reliable transmission components that can convert rotary motion into precise linear motion continues to grow.
SFU ball screws are extensively applied in CNC machines, industrial robots, and automated production systems. By using rolling steel balls between the screw shaft and nut, they enable smooth, efficient linear motion with high positioning accuracy and repeatability. Their high rigidity, low driving torque, and stable performance make SFU ball screws suitable for both high-speed operation and precise micro-feed control. Whether for new equipment design or system upgrades, SFU ball screws provide a dependable solution for precision linear motion applications.
