These Ball Screw Actuators provide high efficiency and high speed in one linear positioning package.
The positive action of the low friction ball screw and nut design provides longer life at load and requires less power to achieve a specified thrust.
Ball Screw Actuators can be used individually, in tandem or as part of a larger mechanical system.
With lifts upto 20 feet, ball screw actuators offer the perfect solution to many linear positioning applications.
- Anti Rotation models are available.
- Move loads and apply force more efficiently than other mechanical actuators.
- Require less power by providing positive mechanical action.
- Permit faster operation and longer life under load.
- Long predicatable ball screw and ball nut life.
- Handles full load in tension or compression.

These Ball Screw Actuators provide high efficiency and high speed in one linear positioning package.
The positive action of the low friction ball screw and nut design provides longer life at load and requires less power to achieve a specified thrust.
Ball Screw Actuators can be used individually, in tandem or as part of a larger mechanical system.
With lifts upto 20 feet, ball screw actuators offer the perfect solution to many linear positioning applications.
- Anti Rotation models are available.
- Move loads and apply force more efficiently than other mechanical actuators.
- Require less power by providing positive mechanical action.
- Permit faster operation and longer life under load.
- Long predicatable ball screw and ball nut life.
- Handles full load in tension or compression.
