High-speed operation and frequent precision positioning are inevitable to generate continuous heat accumulation on standard ball screws, which directly causes thermal expansion, dimensional deviation and reduced positioning accuracy — a core bottleneck restricting the long-term stable operation of high-precision transmission mechanisms. Our Hollow Strong Cooling Ball Screw is professionally developed to target this industry pain point, adopting a mature hollow forced cooling technology to fundamentally control screw temperature rise and suppress thermal expansion. The product features standardized structural design on the screw shaft end, including optimized sealing components and matching supporting bearings. This standardized configuration provides the most effective and cost-efficient solution for thermal expansion reduction, ensuring consistent precision during long-cycle high-speed operation.

To cover more diversified cooling and precision demands, our cooling ball screw series supports two mainstream cooling structures: hollow shaft forced cooling and internal nut cooling. Different from the hollow cooling type, the nut cooling ball screw integrates a built-in cooling structure inside the ball nut, forming a simple, compact and highly efficient cooling system. This structural design solves the cooling difficulty of special ball screws that cannot realize hollow shaft cooling, effectively making up for the application limitations of single cooling mode products. Both cooling structures focus on rapid heat dissipation and stable temperature control, completely avoiding precision attenuation and mechanical errors caused by thermal accumulation.

Wide Application Scenarios

With dual cooling structure options and excellent thermal expansion resistance, the Hollow Strong Cooling Ball Screw is exclusively applicable to high-speed and high-precision industrial scenarios that require long-term continuous operation and strict positioning accuracy. It widely serves high-precision machine tool equipment covering small, medium and large specifications. It is especially suitable for precision machining equipment, high-speed automated positioning systems and continuous-cycle industrial transmission devices that are sensitive to thermal deformation. Whether it is conventional hollow-coolable screws or special structural screws that can only adopt nut cooling, this series can provide targeted temperature control solutions to maintain long-term machining and positioning stability.

Professional R&D and Technical Strength

Focusing on high-speed and high-precision ball screw technical iteration, our team independently develops targeted cooling-type ball screw products for thermal expansion problems of precision transmission systems. We optimize the overall structure from shaft end standardization, sealing matching, bearing coordination to internal cooling channel layout, forming a complete set of mature cooling ball screw design systems. By solving the key technical problem of thermal deformation in high-speed precision ball screws, this series fills the technical gap of stable precision maintenance for long-cycle high-speed operating equipment, possessing strong practical value and technical advantages in the field of precision industrial transmission.

Advanced Processing Technology & Efficient Delivery

We apply standardized and refined processing technology for all cooling ball screw core structures. Both the hollow cooling shaft body and internal nut cooling structure adopt precise forming and seamless matching technology, ensuring unobstructed cooling circulation and stable sealing performance. All shaft end sealing and bearing components are standardized and screened to match the cooling system, maximizing cooling efficiency while reducing assembly and maintenance costs. Optimized processing craft ensures each finished product has uniform heat dissipation performance and durable sealing stability, supporting long-term high-frequency high-speed industrial operation.
