Ballscrew series Cool Type

Ballscrews of Cool Type series are HIWIN's ballscrews with the cooling system designed for the high-speed motion with high dynamic load and precise positioning system. They are made with a hollow screw for additional cooling.

HIWIN's ballscrews with the cooling system



1. Designed for maximum reliability. The computer modeling and analysis are used in the developing of this ballscrew type, that allows to achieve the maximum values.

2. Promotes the ballscrews to a new level of speed characteristics: Dm-N value (up to 200000). The ballscrew with the cooling system allows to eliminate the effects from a high rotation speed (thermal solution) and enhance the rotation speed.

3. Prevention of the thermal distortion. An optimised cooling system allows to minimize the effects of thermal expansion.

4. Durability increase. The friction between the rolling elements leads to the heat generation at the operations with limit accelerations. This can result to the oxidation of the roller elements surface or decarbonization, which leads to the failure. By cooling system these effects are also neutralized.

5. Extension of the lubrication service life. The use of forced cooling slows the thermal aging processes of used lubrication in the system.

6. Maintenance of the constant temperature. The constant cooling of nut and screw for a stable operations of the entire system with constant operating characteristics.

7. Increased accuracy. The thermal expansion is neutralized, that respectively leads to the constant positioning accuracy.

Nut with the cooling type I

The cooling liquid circulates through channels within the nut, removing heat. The liquid, in its turn,  is cooled by the cooler. This nut, in combination with a hollow screw, allows to obtain excellent system with a thermal monitoring and high precision of the positioning.



Nut with the cooling type II

A new generation of the ballscrews for high loads is perfect for constant heavy loads. It is used in the molding machines, presses, power units, replacing hydraulic systems, etc.
