A motor-driven ball screw is a linear actuator that translates rotational motion to linear motion with little friction. A threaded shaft provides a helical raceway for ball bearings which act as a precision screw. As well as being able to apply or withstand high thrust loads, they can do so with minimum internal friction. They are made to close tolerances and are therefore suitable for use in situations in which high precision is necessary.
Today motor-driven ball screws have been engineered to be miniature and suitable for robotic surgical tools as well as designed to deliver capacities in excess of 1 million newtons.
Motor-driven ball screws may be used in:
- Lab equipment
- Large machine tools
- Large manufacturing equipment
- X-Y, X-Y-Z positioning equipment
Motor-driven ball screw may be found in products such as:
- CNC machine tools
- Equipment used to test aerospace sensors
- Hexapod equipment used in positioning applications
- Manufacturing lathes
- Microscopes used in labs and semiconductor manufacturing environments
- Surgical tools
