Special Actuators

See our newest custom actuator case study here!

A customer came to us recently to design and build a new product from the ground up. They needed to build a new bottling machine to handle filling their customer’s unique bottle design with very caustic materials.

Once we determined the full requirements, we designed and manufactured a new rotary actuator with an attached gripper unit, all in 316 stainless steel to provide protection in from corrosive materials. The new actuator and gripper grips the bottle, rotates it the desired degrees for filling, then rotates back to release the bottle.


Rotary Gripper Unit


Rotomation welcomes requests for special actuators because we understand how they can save our customers money by reducing cost of extra parts or engineering time and/or improving their product or process. About 40% of the actuators we produce have some non-standard feature that improves our actuator's ability to adapt to the load and/or working conditions in order to better fit our customer's application.

We stock blanks of many parts that can be modified quickly and easily to provide the majority of simple changes, usually with no effect on lead time. Complex modifications may require new parts and might take additional time for manufacturing, but are often justified. Moreover, special actuators sometimes require the development of completely new actuators designed around your specifications but based on the same principles as our standard actuators, which can be done in a timely manner also.

For more specialized applications or actuators that do not conform to the same principles of our standard product line, our expert team of design engineers will work with you to establish specifications tailored to meet your specific requirements, then they will design, develop and test a new product from the ground up if required. Whether you need one unit or thousands, we will produce what you need quickly and at a reasonable price.

We assign a special code in the part number of every special actuator that points to a unique bill of material that contains all the specifications and modifications necessary to reproduce a specific special actuator to simplify reordering. Upon request, we can also declare a special actuator to be proprietary to the OEM or distributor who ordered it originally to protect their investment.

Custom-made Actuators

If your application requires an actuator completely different from the products we offer, in form and/or function, we have a solution for your application. See a few examples of our latest custom-made actuators below.



Customized Actuators

If your application requires a simple modification to one or more parts on one of our standard units or you need us to make one of our standard actuators in some other material due to special environmental requirements, we'll be glad to help you. See a few examples of recent customizations made for some of our customers below.
