    Maximum Reliability: Rotomation actuators are built for high cycle rates and long-life expectancy, backed by our basic 2-year limited warranty. Typically, our actuators run for tens of millions of cycles. Key features include: 

    Pinion Shafts:Made from quenched and tempered 4150 steel, ensuring extreme impact resistance, accuracy, and long life. 

    Floating Pistons and Racks:Designed for maximum reliability and fault tolerance. 

    Replaceable Sintered Bronze Rack Bearings:Offer long life and easy repairability. 

    Oversized Ball Bearings:Capable of handling heavy loads, allowing for substantial hollow shafts and special applications. 

    Robust and Efficient Design:Our fully machined body, oversized bearings, and rugged shafts allow the actuator to serve as the bearing for your load. This design reduces the number of parts, simplifies design efforts, and saves space. We keep blank pinion shafts with full bearing bore diameter and extra length in stock, enabling us to quickly create custom shafts tailored to your design needs. 

    Long-Lasting and Rebuildable:Rotomation actuators are built to endure millions of operations under heavy loads and are fully rebuildable. We offer a fast rebuild service or provide parts for self-repair. 

    Longevity and Support: Our customers often share stories of Rotomation actuators that have been in service for 10, 20, or even 30 years. They are pleased to learn that we support nearly all our old products and that our current models are compatible with older versions, despite continuous improvements for longer life. Each unit is serialized, and we maintain detailed records indefinitely.

  Actuator Motion Options

Choose your motion then configure the unit to suit your needs exactly.

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.
