Product detail
The SFI Ball Screw Series is a high-precision linear motion component designed for accurate positioning and efficient power transmission. Engineered with advanced thread grinding and precision machining, SFI ball screws offer exceptional smoothness, low friction, and high rigidity, making them ideal for CNC machines, robotics, and industrial automation systems.
Each SFI ball screw features hardened steel shafts and recirculating ball nuts that ensure consistent motion accuracy and extended service life. The preloaded design eliminates backlash, allowing for high repeatability even under high-speed and heavy-load conditions.
Whether you need a compact drive solution or a heavy-duty linear actuator, the SFI series provides the stability, efficiency, and precision required in modern industrial applications.
Highlight Feature
Internal Circulation, Flange Type SFNI & SFI series delivers high smoothness, high rigidity and high durability. With strong dust-proof design, SFNI & SFI series prevents abnormal chips getting into the nut extending service life, making SFNI & SFI series applicable to contaminative environment.
High Precision Transmission
Ground thread design ensures stable positioning and smooth motion.
High Efficiency
Rolling contact between balls and screw reduces energy loss compared to traditional lead screws.
Low Backlash
Preloaded nut design provides accurate, repeatable linear movement.
Long Service Life
Made from hardened, wear-resistant alloy steel.
Compact & Rigid Structure
Suitable for space-limited automation systems.
Smooth & Quiet Operation
Optimized ball circulation path reduces vibration and noise.
