Protection Options

Washdown Protection

Our washdown protection option for actuators can be used in applications where water ingress protection, corrosion resistance, and leak contamination prevention are paramount. Rotomation also offers fluoroelastomer (FKM) seals for washing down with high-temperature caustic cleaning solutions.  Shaft seals are built into the body or integral cover plates, cylinders are sealed by O-rings, and assembly threads are sealed.  We use stainless shafts with anodized body and end caps. Also available are hard chrome-plated shafts and electroless nickel-plated body and end caps.  See diagram.

Note the easily cleaned, uniform finish. The reliability and durability of these units largely eliminate the remove-and-replace production interruptions needed for units with less chemical resistance. We can produce just about any of our actuators in a suitable stainless alloy upon request. When nothing else will hold up, your customers will save money going with stainless steel.


Solutions That Fit Your Specific Needs

Rotomation offers extreme flexibility in options for you to configure your actuator to suit your needs exactly, rather than compromising your design to accommodate a one-size-fits-all actuator. Many times a simple modification to the shaft size, projection, or machined features such as keyways, flats, thru holes, etc., can improve your product and reduce cost. Or, you might need the actuator's main body and end caps to be made of an alternative material like stainless steel or plastic, instead of the standard anodized aluminum alloy. A custom mounting hole pattern might make our actuator drop into your current setup. Rotomation understands your needs and is dedicated to providing solutions that allow you to optimize your design.

Indexing Drives For Automation

There are many applications in automation calling for repetitive rotary indexing. Some examples:

  • star wheels
  • conveyors
  • escapements
  • parts positioning for labeling, machining, inspection, etc.
  • dispensing

There are at least three types of indexing drives that the engineer can choose between for these applications:

  • Mechanical cam based drive
  • Electrical servo based drive conveyors
  • Pneumatic indexing drive


Cam Drives

Cam drives have been used for many years and are capable of good accuracy and dynamic control, high speed, and heavy loads. They are typically driven by a gearmotor, with one revolution of the input for each incremental motion of the output. They are best suited for continuous indexing which does not require the motor to be started and stopped for each cycle.

Example of a Cam Drive Indexer

  • Good dynamic control
  • Good accuracy
  • Large load capacity
  • Durable, rugged construction
  • Energy efficient
  • High cost
  • Not ideal for index-on-demand
  • Inflexible operation


Servo Based Indexing Drives

A servo based indexing drive for such an application will include a servomotor with or without a gearbox, an encoder for position feedback, a motion controller, and an amplifier. Some of these components may be combined into integrated packages. There is normally a system controller overseeing the motion control, including human interface.

Example of a Servo Based Indexing Drive

  • Fully programmable speed, index, direction, acceleration, etc.
  • High resolution
  • Good dynamic control
  • Flexible; can be repurposed easily
  • Relatively complex and expensive
  • Sensitive electronics and wiring must be shielded from adverse environments
  • High level of know-how to design and repair


Pneumatic Indexing Drives         

Pneumatic indexing drives, such as our indexing actuators, are simple, mechanical components capable of repetitive rotary indexing with no accumulating error. They are based on rack-and-pinion rotary actuators with the addition of one-way roller clutches and a ratchet and pawl system for stopping and registration. The motion is initiated by a directional control valve, so they are well suited to flexible automation where the index must occur on demand. They are robust and durable, but cannot match the controlled motion characteristics of the servo or cam drives.

Rotomation's X2 Indexing Drive

  • Low cost
  • Very simple to design, implement, and maintain
  • Robust construction can support the rotating load with its own bearings
  • Operate in harsh environments
  • Poor dynamic control of load
  • No programmability
  • Air consumption (only when moving)


Energy Consumption

The relative amount of energy these drives consume will depend on the duty cycle of the application. Cam and servo drives are both quite efficient but differ in that the servo uses full power to hold the load in place whereas the cam drive uses power only when driving the load. A pneumatic indexer uses compressed air, which is less efficient than an electric motor drive, but also uses no power when in the locked condition. So, if the duty cycle includes a high percentage of dwell time, the advantage shifts toward the cam and pneumatic systems.

Proudly Made in the USA

What's Unique About Us?

Rotomation manufactures high speed, heavy duty pneumatic actuators that produce several shaft motions. All products are extremely configurable, which separate us from our competitors and give users maximum flexibility in their design. Another unique advantage we have is our ability of supplying special actuators quickly and at a reasonable price.

Unique Products

Like all of our competitors, we have a basic line of bidirectional actuators that rotate between two positions. Like some of our competitors, we also carry a line of multi-position actuators that rotate between three, four, or five positions in any sequence and a line of multi-motion actuators that combine linear stroke with rotary motion, independently-controlled but all in one actuator. But here are a few aspects that set us apart from our competitors.

We offer a line of unidirectional actuators that rotate in increments and prevent backward rotation. These actuators are divided in two main families, stepping and indexing.

X4 Indexer showing motion

Our popular indexing actuators, like the X4 shown on the image on left, provide precise and repeatable stopping capability with no accumulating error and very high accuracy within ±0.2 degrees. There is no other actuator of its kind available on the market and they are often used to replace servo motors or cam-based drives at a far lower cost, without its unnecessary complexity. Learn more about how they work here.

Common applications: index tables, indexing conveyors, star wheels, walking beams

S4 Stepper Motion

Our rugged stepping actuators, like the S4 shown on the image on left, will provide torque over a fixed angle but unlike our indexing actuators, they don't have stopping capability. Unlike our indexing actuators, our stepping actuators can go over 360 degrees (over 1 revolution) with standard rotations up to 730 degrees and rotation angle can be reduced by up to 30 degrees with our stroke adjusters. These actuators are resilient as they are self-contained units with hefty shaft bearings to assure best concentricity rather than the modular add-on clutch adapters offered by our competitors.

Common applications: used as drives for conveyors, roll/material feeders, detented or shot-pinned loads

PX2 Nitpicker Motion

Our unparalleled line of nitpicking actuators, like the PX2 shown on the image on left, provide both rotary and linear motion, independently-controlled, but has indexing rotary motion instead of the regular rotary motion in our pick and place actuators. Like the indexing actuators above, our nitpickers provide unidirectional rotation in precise, repeatable steps with no accumulating error, in addition to linear motion with standard strokes up to 12 inches.

Common applications: sequential assembly and/or testing, indexing applications requiring extension/retraction motion to pick a workpiece and process it

Our family of compact actuators include a variety of rotary actuators such as our A032, that provide more torque and bearing capacity than any other actuator of similar size on the market, our AL75 with its characteristic slow start/stop motion inherited from its patented drive mechanism that is unlike any other rotary actuator we offer. Image below shows a group shot of our three compact rotary actuators.

Compact rotary actuators, patented AL75, robust A032, and powerful A752

Unique Quality

All our actuators are manufactured with the highest degree of quality, surpassing the industry standard. Our pneumatic actuators are therefore capable of high speed cycle rates and feature an inherent heavy duty construction, only matched by hydraulic actuators. Our actuators are used in harsh environments such as in metal working applications, electronic and mechanical assembly applications, demanding testing applications, food packaging applications, and semi-automated bakery production lines, among others. Our actuators are so reliable and durable that they are very popular among the automotive, semiconductor, food, and pharmaceutical industries.

We use nothing but the best and highest quality materials available in our product lines and always design for maximum ruggedness, reliability and durability. Materials such as 2024 aluminum and 4150 heat-treated steel are commonly used in the manufacturing of our parts and we use the latest and greatest coatings and treatments to ensure maximum endurance. We also offer alternate materials to accommodate specialty applications requiring enhanced corrosion resistance and/or clean environments.

Unique Application

Whether your application requires a unique feature on a standard unit or a completely new actuator, we have a solution for your unique application. About 40% of the actuators we produce require some special feature or modification, or in some cases, they are completely new products, depending in the application and the customer's request. Click to see examples of our latest customized and/or custom-made actuators.

Unique Satisfaction

Our attention to detail and unique team of knowledgeable technicians and professionals stand behind the quality of our products to ensure your satisfaction and reliable performance for millions of duty cycles and years to come. Furthermore, our excellent sales and engineering team will guide you through the process of selecting and specifying your actuator to satisfy your specific needs, to help you meet and exceed your production expectations and be there for you if you need any kind of support along the way.

Here at Rotomation, Inc., you get targeted engineering services, personalized customer service and unique technical support, all included in the price of the actuator. So when you choose our products, you get our expertise; it's that simple!


Special Actuators

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.

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. Below is an example of a custom-made rotating gripper.
