The DFU Series Ball Screw is a high-performance precision motion solution engineered for industrial applications requiring extreme compactness and silent operation. By utilizing an advanced internal circulation structure—featuring circular or elliptical reversers—the balls circulate seamlessly within the nut, significantly reducing the physical footprint and operational noise levels.
Designed for mission-critical precision, the DFU series incorporates a specialized double nut preloading mechanism. This strategic design effectively eliminates axial clearance, ensuring superior positioning accuracy and stability, making it an ideal choice for high-precision machinery and automated linear motion systems.

Q: What is the benefit of internal circulation in the DFU ball screw?Internal circulation allows the balls to return within the nut itself, resulting in a more compact design and significantly reduced noise compared to external return systems.
Q: How does the double nut design improve accuracy?The double nut configuration allows for preloading, which eliminates axial clearance (backlash), ensuring that the machine reaches its target position with maximum precision.
Q: In which industries are these rolling bearings and ball screws typically used?They are widely used in CNC machinery, semiconductor manufacturing, medical devices, and any automation equipment requiring high-precision linear motion.
Q: What does the C3 designation typically refer to in these components?C3 refers to the internal clearance grade, indicating a specific tolerance level that balances thermal expansion and precision for industrial performance.
Q: Can DFU ball screws be integrated into existing linear modules?Yes, the DFU series is designed for compatibility with standard linear modules, providing an upgrade in accuracy and noise reduction.
Q: How often should the internal circulation system be lubricated?Lubrication intervals depend on the load and speed, but regular maintenance is critical to ensure the reversers function smoothly and to prevent premature wear.
