DFI Series Ball Screw

DFI Series Ball Screw

Product Descriptions

The DFI Series Ball Screw is a high-rigidity, precision mechanical component engineered to efficiently convert rotational input from a motor into extremely accurate, reliable linear output. The design focuses on maximizing positional accuracy and dynamic performance, making it a critical component in the most demanding automation and machine tool applications.

Key Functional Features

The DFI Series is characterized by its superior operating characteristics, making it essential for precision motion control:

Zero-Backlash Operation: Achieved through the preloaded double-nut design. The nuts are slightly offset, forcing the steel balls into constant contact with both the screw shaft and the nut raceways. This eliminates the axial gap (backlash) and ensures immediate, precise response to command.

High Rigidity: The double-nut preloading significantly increases the system's axial rigidity, allowing it to withstand heavy thrust loads without compression or extension, thus maintaining positional integrity.

High Positional Accuracy: Manufactured to extremely tight lead accuracy grades, the DFI Series guarantees exceptional positional accuracy and repeatability necessary for sophisticated operations.

High Dynamic Performance: The rolling element principle (steel balls rolling in precision-ground grooves) ensures highly efficient, low-friction power transmission, enabling high-speed movement with minimal drive power requirements and less heat generation.

Heavy-Duty Solution: The robust construction is optimized for sustained high-load, high-duty cycle industrial use.
