DFU6310 Ball Screw

DFU6310 Ball Screw

Product descriptions

The DFU6310 Ball Screw Assembly represents the pinnacle of industrial linear motion power. Designed as an ultimate-duty, monumental-sized component, it is engineered for the largest machines requiring an uncompromising combination of massive load capacity, structural rigidity, and absolute zero-backlash positioning.

Featuring a colossal 63mm shaft, this assembly provides maximum buckling resistance and stability, even over extended stroke lengths. It is paired with a 10mm lead for efficient rapid travel and a preloaded Double Nut (DFU) configuration that eliminates backlash for vibration-free machining. Capable of handling static loads exceeding 20 tons, the DFU6310 is the definitive solution for Horizontal Boring Mills, Aerospace Gantries, and Heavy Industrial Presses where failure is not an option.

Performance Characteristics

Industrial-Scale Rigidity with Zero Backlash
The DFU6310 Ball Screw is engineered specifically for the heavy machine tool sector. While single-nut versions (SFU6310) are suitable for general transport, the DFU6310 is purpose-built for precision machining. By combining the immense structural strength of a 63mm shaft with the zero-backlash precision of a preloaded Double Nut, it serves as the standard solution for driving the heavy columns of horizontal boring mills and gantry machining centers.

Stability Over Extended Lengths
In large-scale aerospace applications, X-axes often span 6 meters or more. At these lengths, standard 50mm shafts suffer from gravitational sagging and "whipping" (vibration). The robust 63mm core of the DFU6310 minimizes deflection, ensuring high-precision positioning even at the center of the travel stroke where structural rigidity is most critical.

Heavy-Duty Industrial Durability
Designed for continuous 24/7 operation under extreme loads, the DFU6310 features large rolling elements (typically 1/4" diameter) and induction-hardened raceways. The preloaded double-nut design effectively distributes stress across more ball circuits, ensuring an extended service life even when manipulating payloads exceeding 10,000 kg.
