DFU2005 Ball Screw

DFU2005 Ball Screw

Product descriptions

The DFU2005 Ball Screw Assembly stands as the industry standard for precision CNC machining. As a heavy-duty, standard-pitch linear motion component, it delivers the perfect balance of structural rigidity, efficient travel, and absolute zero-backlash positioning.

Featuring a robust 20mm nominal shaft paired with a standard 5mm lead, the assembly utilizes a preloaded Double Nut design to completely eliminate axial play and chatter. This configuration ensures maximum stiffness and bidirectional accuracy, making the DFU2005 the ideal choice for metal-cutting CNC routers, mill retrofits, robotics, and demanding industrial automation requiring repeatable, zero-lost-motion movement.

Key Features & Engineering Advantages
1.Absolute Zero-Backlash: The factory-preloaded Double Nut design completely eliminates axial clearance. This ensures the highest level of positional accuracy, repeatability, and smooth motion during direction reversals.
2.High Axial Rigidity: The combination of the preloaded nut assembly and the robust 20mm shaft provides superior stiffness. This design effectively resists deflection and vibration, even under heavy cutting loads or rapid acceleration.
3.Versatile 5mm Lead: The standard 5mm pitch offers an optimal balance between positional resolution and travel speed, making it the versatile choice for the majority of general-purpose and heavy-duty industrial automation tasks.
4.Robust Structural Profile: The 20mm shaft diameter provides high column strength and substantial load capacity, perfectly suited for medium-to-heavy-duty industrial applications.
5.High Transmission Efficiency: Utilizing rolling contact mechanics, the system achieves an efficiency typically exceeding 90%. This minimizes power consumption and reduces heat generation during continuous high-force operation.
6.Rigid Flange Mounting ("F"): The robust, flanged ball nut ensures a simple, highly rigid, and secure attachment interface for the machine's moving carriage plate.
