THK’s SDA V and SDA VZ Series Ball Screws represent precision-engineered linear motion components fully compliant with DIN standards, ensuring seamless integration and reliable performance in demanding industrial applications. These ball screw assemblies are designed with a compact, high-rigidity structure, featuring a single-nut design that optimizes space while maintaining exceptional load capacity and positional accuracy. The SDA V Series offers standard precision grades suitable for general automation tasks, while the SDA VZ variant incorporates advanced preloading mechanisms and enhanced sealing options to deliver superior smoothness, minimal backlash, and extended service life in harsh environments. Both series utilize high-grade steel for the screw shaft and precision-ground ball grooves, paired with durable circulating components that ensure consistent torque stability and efficient force transmission across millions of cycles.

Key technical features include DIN-standard flange dimensions for straightforward mounting, optional preload adjustments to eliminate axial play, and integrated seals that protect against contaminants like dust, chips, and moisture. The ball screws achieve high positional accuracy through precise lead accuracy control, with repeatability errors held within microns. Their optimized ball circulation system reduces vibration and noise, contributing to smoother operation at high speeds. Performance advantages are evident in their ability to handle combined loads—axial, radial, and moment loads—without sacrificing efficiency. The low friction coefficient of the ball-to-groove interface ensures high mechanical efficiency, typically exceeding 90%, which translates to reduced power consumption and heat generation. This efficiency, combined with robust construction, allows for continuous operation at elevated speeds while maintaining positioning stability, even under variable load conditions.

In industrial machinery, these ball screws are integral to CNC machining centers, where they provide precise table positioning and feed motion for milling, drilling, and grinding operations. Their rigidity and accuracy minimize deflection during heavy cutting tasks, enhancing surface finish quality and tool longevity. Automotive manufacturing systems leverage SDA V and SDA VZ ball screws in robotic welding arms, assembly line transporters, and precision testing equipment, where repeatable linear motion is critical for alignment and throughput. The series’ resistance to wear and contamination makes them ideal for automotive paint shops or stamping presses exposed to particulate debris. Within precision equipment, these components drive motion in semiconductor lithography machines, optical positioning stages, and medical device actuators, demanding sub-micron accuracy and minimal maintenance. Their DIN compliance further simplifies global sourcing and replacement, reducing downtime in multi-vendor production environments. By balancing durability, precision, and adaptability, THK’s SDA V and SDA VZ Series Ball Screws serve as foundational elements in advancing automation and technological innovation across sectors.
