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.
