Dene your application

Choice of application area also means choice of design. With SKF rotary actuators you can meet the demands of advanced installations. Economic requirements can also be satisfied through the use of a simpler solution. Speed can vary from a fraction of a second up to several minutes or more. You can use many different types of drive. This usually takes the form of an electric motor.

The output shaft can be supplied with either an external or internal keyway, or specially designed to suit. Control techniques may vary, from advanced computer systems to simpler methods. If required, we can supply your rotary actuator with electrical Limit switches and me-

chanical position indicator or potentiometer for positioning control. Mechanical emergency operation (hand crank) is standard on all SKF rotary actuatotrs.

Choose the precision you need

Let the precision requirements determine the choice of your rotary actuator. In demanding high-speedapplications with a high duty factor, the natural choice is a rotary actuator which incorporates an SKF ball screw. These are tried and tested, highly efficient units. Rotary actuators

fitted with ball Screws operate without backlash throughout their working life, as they are pre-loaded at all points of contact. Use of the ball screw permits a very high degree of angular resolution, as well as positional stability and precision. In less demanding applications with a low duty factor you could choose a rotary actuator with acme screw. This solution also provides you with a self-locking SKF rotary actuator.
