Model BTK-V SERIES

THK’s Ball Screw Transport Ball Screw Model BTK V SERIES represents a significant advancement in precision linear motion technology, engineered specifically for high-load transport applications where reliability, accuracy, and durability are paramount. This series incorporates a unique ball circulation system that ensures smooth, consistent motion even under demanding operational conditions, making it an ideal solution for industrial machinery, automotive manufacturing systems, and precision equipment requiring exact positioning and repeatability.

Key technical features of the BTK V SERIES include its compact design, which allows for space-saving integration into machinery without compromising performance. The ball screw utilizes high-grade materials and advanced heat treatment processes to enhance surface hardness and wear resistance, significantly extending service life. Precision grinding of the screw shaft ensures high lead accuracy, with minimal deviation, contributing to superior positional precision. The nut design incorporates a large number of load-carrying balls, distributed evenly to handle substantial axial loads while maintaining low friction and minimal heat generation. Additionally, the series is available in various accuracy grades and preload levels, allowing customization to meet specific application requirements, from general-purpose transport to high-precision tasks.

Performance advantages of the BTK V SERIES are evident in its ability to deliver high efficiency and stability. The optimized ball circulation path reduces vibration and noise, enabling smoother operation at high speeds, which is critical in automated production lines and precision assembly systems. Its high rigidity and load capacity make it suitable for applications involving heavy loads, such as material handling in industrial machinery or positioning in automotive robotic arms. The ball screw’s low maintenance requirements, due to its sealed design that protects against contaminants like dust and chips, reduce downtime and operational costs. Moreover, its energy-efficient operation, achieved through reduced torque requirements, contributes to lower power consumption in continuous-use scenarios.

Typical applications span across multiple sectors, including industrial machinery where the BTK V SERIES is used in CNC machine tools, injection molding machines, and packaging equipment for precise linear movement and load support. In automotive systems, it finds use in assembly robots, brake forming presses, and test rigs that demand repeatable accuracy under high stress. For precision equipment, this series is employed in semiconductor manufacturing devices, medical imaging systems, and optical alignment instruments, where micron-level precision and reliability are essential. By combining robust construction with advanced engineering, the THK BTK V SERIES ensures enhanced productivity and longevity, making it a trusted choice for engineers seeking dependable linear motion solutions in challenging environments.
