High helix ball screw
300 kgf, max 75 m/min | COOL HIWIN

The cool type series uses forced cooling fluid that, when passed through the nut, minimizes heat generation and thermal expansion.
Applications:
- Cool type 1 + hollow shaft design: high speed machine tools and machining center.
- Cool type 2: electric-driven injection machines, presses, power units and other replaceable hydraulic drives.

Optimized design for high reliability : Good thermal protection and high reliability.

Promotes higher speed rotation : Will eliminate high-speed rotation aftereffect

Prevents thermal distortion : Optimized heat transfer design minimizes heat generation

Improved durability : Heat can cause balls to become oxidized or decarburized.

Extended lubricant life cycle : Reducing the heat inhibits deterioration of the lubrication.

Uniform temperature/Reduces warm-up time : Nut & shaft cooling effect keeps feed-system temperature constant.

Higher feeding accuracy : Cooling effect will stabilize against thermal expansion.
