SFV Series Ball Screw

SFV Series Ball Screw

The SFV Series Ball Screw is a heavy-duty linear actuator engineered for exceptional performance in demanding, high-load, and high-speed industrial environments. It is a premier choice for precision machine tools, CNC machinery, and various high-speed industrial applications where strength and durability are critical.

This series is distinguished by its robust flanged nut and an external "end-cap" ball recirculation system. This design choice specifically enables the ball screw to handle high feed rates and absorb significant impact loads, ensuring reliable and consistent operation under stress.

Available in Two Manufacturing Variations:

Rolled Screws: This option offers a strong and cost-effective solution suitable for many industrial applications.
Ground Screws: For applications requiring the highest level of precision and smoothness, ground screws are available, manufactured to tighter tolerances.

Manufacturing Processes and Procedures

The superior quality of the SFV Series is the result of a meticulous and controlled manufacturing process:

Material Selection: Begins with high-grade steel, inspected for strength and durability.

Threading: Screw shafts are formed by either cold-rolling for strength and efficiency (C7 grade) or precision grinding for the highest accuracy (C3/C5 grades).

Heat Treatment: Both the screw and nut undergo induction hardening to create wear-resistant surfaces, ensuring a long fatigue life.

Precision Machining: The nut's internal grooves are ground to perfectly match the shaft, enabling smooth ball circulation.

Assembly and Preloading: Components are meticulously assembled, and a specific preload is applied to eliminate backlash and increase rigidity.

Quality Control: Every ball screw is rigorously tested for lead accuracy and operational smoothness before dispatch.
