DFU1610 Ball Screw
DFU1610 Ball Screw
Product descriptions
The DFU1610 Ball Screw Assembly is a high-performance linear motion component designed to combine high-speed capability with precision rigidity.
Uniquely engineered for zero-backlash operation, the DFU1610 features a preloaded Double Nut design that eliminates axial play, ensuring accurate bi-directional movement. Paired with a steep 10mm lead, this assembly achieves rapid linear travel without sacrificing stability. It is the ideal choice for dynamic, high-accuracy applications, including high-throughput automation, laser engraving machines, and high-speed pick-and-place robotics.

Key Engineering Advantages
1.Elimination of Reversal Error (Zero Backlash):
Standard single-nut designs (like the SFU1610) possess a small amount of internal clearance (backlash) between the balls and raceways. During high-speed reversals, this creates a "dead zone" or lost motion. The DFU1610 eliminates this via internal preload, ensuring immediate engagement: the instant the motor reverses direction, the load moves without delay.
2.Dynamic Stiffness & Damping:
High-speed acceleration and deceleration naturally generate vibration. The preloaded double-nut configuration acts as a structural stiffener, increasing the rigidity of the connection between the screw and the load. This minimizes vibration and reduces "ringing" (settling time) when the machine comes to a rapid stop, resulting in smoother motion.
3.Cycle Time Optimization:
The DFU1610 allows for operation at high feed rates (20m/min+) without compromising accuracy. This capability enables machine builders to minimize travel time during rapid traverses while maintaining the precision needed for fine detail work, significantly optimizing overall cycle times.
