The NSK Ball Screw Cooling System provides a simple design that delivers higher accuracy and higher speed for a large variety of machine tools.

NSK realized the “Built-in Nut Cooling System” to enable a drive system to be more accurate and faster, even for a long ball screw that is hard to apply a conventional hollow shaft-cooling system.

Nut Cooling Ball Screws

Features

1. The NSK Built-in Nut Cooling System is applicable for both offset-lead preload type and double-nut preload type ball screws.
Offset lead preload type: more compact using only a single ball nut.
Double nut preload type: larger preload is available with two ball nuts.

2. Coolant circulates in the nut in a balanced manner, effectively cooling the ball screw.

3. Designed so that the preload torque does not increase even when the nut is cooled.
