    Rotary Actuators Configured for Your Application

    At Rotomation, we manufacture high-speed, heavy-duty pneumatic, and low-pressure hydraulic rotary actuators with various shaft motions. Our design and engineering team will get you the product that fits your requirements.

    Choose rotation options from a bidirectional rotation between two, three, four, or five positions, and unidirectional rotation in steps. Each rotary motion can be combined with linear motion in a single, independently-controlled actuator.  

    Our actuators are used in applications for metalworking, assembly, testing, and packaging machinery for automotive, semiconductor, food, pharmaceutical, and other industries.

    Their customization and configurability mean you can specify an actuator that will optimize the design of your machines.
