Model SDAN-V-SDAN-VX SERIES

The THK Ball Screw SDAN V and SDAN VX SERIES represent a pinnacle of engineering precision, designed to meet the rigorous DIN standards for reliability and performance in demanding motion control applications. These compact, high-rigidity ball screws are engineered with a unique single-nut design that incorporates a large lead and optimized ball circulation path, ensuring smooth, efficient linear motion with minimal friction and exceptional positional accuracy. The SDAN VX variant further enhances this with preloaded nuts, delivering zero backlash and heightened stiffness for applications requiring ultra-precise positioning and resistance to vibration or external forces. Both series feature precision-ground shafts with hardened steel construction, offering high load capacity and durability, while their compact dimensions make them ideal for space-constrained installations in industrial machinery, automotive systems, and precision equipment.

Key technical features include compliance with DIN 69051 standards, ensuring interchangeability and consistent quality across global applications. The ball screws utilize a return tube-type ball circulation system, which minimizes noise and heat generation during high-speed operation, extending service life even under continuous use. With lead accuracy grades of C5 or higher, these components guarantee repeatable motion control, critical for tasks where micron-level precision is non-negotiable. The SDAN V SERIES supports standard precision needs, while the SDAN VX SERIES caters to high-precision scenarios with its adjustable preload mechanism, allowing fine-tuning to counteract wear over time and maintain performance integrity. Both models are available in a range of shaft diameters and leads, providing flexibility to match specific torque, speed, and load requirements without compromising on efficiency.

Performance advantages of the SDAN V and SDAN VX SERIES translate directly into operational benefits across diverse sectors. Their high efficiency, often exceeding 90%, reduces energy consumption and heat buildup, contributing to lower total cost of ownership. The robust design withstands heavy loads and moment forces, making them suitable for applications involving frequent starts, stops, or direction changes. In industrial machinery, these ball screws drive CNC machine tools, robotic arms, and automated assembly lines, where precision and reliability minimize downtime and enhance productivity. Automotive systems leverage their durability in electric power steering mechanisms, transmission testing equipment, and brake assembly robots, ensuring safety and compliance with stringent industry standards. For precision equipment, such as semiconductor manufacturing devices, medical imaging systems, or optical alignment instruments, the zero-backlash and high-rigidity characteristics enable sub-micron accuracy, critical for producing defect-free components and maintaining process consistency. By integrating THK’s SDAN V and SDAN VX SERIES, engineers achieve seamless motion control that boosts efficiency, accuracy, and longevity in even the most challenging environments.
