The DFV Series is a heavy-load, external circulation ball screw designed for high rigidity, high speed, and precise linear motion.

This specialized double-nut ball screw model is selected when the rigidity and high thrust of a double-nut system are required, with an added focus on operational smoothness, noise reduction, or a specific structural profile.

DFV Series Performance Highlights
Heavy-Duty Return Tubes: Reinforced external circulation pipes absorb shock loads and prevent ball jamming during high-impact cuts.
Preloaded Zero Backlash: Double-nut configuration eliminates axial clearance and significantly enhances structural stiffness.
Tangential Pickup Geometry: Smooth ball entry into return tubes dampens acoustic noise and reduces impact fatigue at high speeds.
Massive Load Ratings: Dynamic capacities up to 15,000+ kgf and static capacities exceeding 54,000 kgf on large-scale models.
Applications: Heavy-duty CNC boring mills, horizontal machining centers, forging presses, and high-tonnage actuators.
