DFU3208 Ball Screw

DFU3208 Ball Screw

Product descriptions

The DFU3208 Ball Screw Assembly is a high-performance linear motion component designed for heavy-duty applications requiring superior stiffness and speed.

The model designation "DFU" indicates a Double Nut configuration. Unlike standard single-nut (SFU) designs, the double nut structure allows for higher preload and more load-bearing balls, resulting in exceptional rigidity and the elimination of backlash. Featuring a robust 32mm shaft and an optimized 8mm lead, this assembly efficiently converts rotational motion into smooth linear travel. It is the ideal solution for demanding CNC machinery, robotics, and industrial automation where high accuracy and load capacity are critical.

Key Features & Specifications
DFU Series Designation: The "DFU" classification indicates a Double Nut configuration. Compared to standard single-nut (SFU) types, this design features a longer nut body and a higher number of internal load-bearing balls. This results in significantly higher load capacity, superior structural rigidity, and the elimination of backlash.
Dimensional Profile:

• Nominal Diameter: 32mm (High column strength for stability).
• Lead (Pitch): 8mm. The nut advances linearly by 8mm for every single revolution of the shaft.

High Precision: Engineered to achieve minimal positioning deviation and excellent repeatability, allowing for fine feed control in critical processes.
High Efficiency: Utilizes rolling ball bearing elements to minimize friction, resulting in transmission efficiency typically exceeding 90% and reduced heat generation.
Applications: Ideal for heavy-duty CNC machinery, industrial robotics, large-scale automated equipment, and precision instrumentation.
