THK Presents Ball Screw with Integrated Nut Cooling

Efficient temperature control for superior precision and reliability
The new nut cooling solution for ball screw drives enables targeted and effective heat dissipation in applications with high speeds and thermal loads. Specially designed cooling channels inside the nut reliably dissipate the heat generated during operation. The result is significantly improved thermal stability – while maintaining consistently high positioning accuracy and a constant preload torque.

Application-specific optimized cooling design
The cooling channel design is configured individually — tailored to the respective preload method and specific customer requirements. This ensures maximum cooling performance and high system efficiency. Thanks to its modular design, the cooling system can be flexibly integrated into a wide range of ball screw drives — regardless of shaft diameter, recirculation system or preload concept. This opens up new possibilities across numerous industrial applications.

Efficient cooling even for long ball screws
For long ball screws where implementing a hollow shaft is often technically challenging, nut cooling offers a high-performance alternative. It ensures effective thermal management particularly in demanding applications with limited space for cooling systems.
