Hundreds of precision ball screw different designs to meet virtually any performance criteria.

Our ball screws can be supplied completely machined and assembled with nuts, flanges, wipers, and EZZE-MOUNTS. Ball nuts are offered in standard and preloaded designs. 

If a standard assembly does not fit the application, Nook can machine a ball screw to your specific design requirements. Custom sizes and configurations are available.

Ball Screw Advantages
Ball screws offer a highly efficient means of converting rotary motion to linear motion. Precision ball screws have several bearing balls that transfer the load between the nut and screw.

Improves speed, force, and duty cycle
Longer and predictable life cycle
Requires less motor power
Heavier loads
Greater accuracy
High efficiency (less friction)
Ball screws are cataloged by screw thread accuracy: standard rolled, precision rolled and ground.
