Rotomation Product Line: Harnessing the Power of Rotation

At Rotomation, we specialize in providing robust and reliable actuators that deliver exceptional rotary motion. Our diverse product line includes pneumatic and low-pressure hydraulic actuators, each meticulously engineered to meet the demands of various applications. Whether you need smooth reciprocating rotation, stepping motion, or accurate indexing, Rotomation has the perfect solution. Our actuators utilize a powerful rack and pinion mechanism, where pressurized fluid drives a piston, pushing a rack, rotating a pinion gear for accurate and controlled movement.

Explore our range of rotary, stepping, indexing, and pick-and-place actuators to discover how Rotomation can enhance your automation and motion control needs.

Rotary

Rotary Actuators: Need precise back-and-forth rotation, like a windshield wiper? Our mini and compact rotary actuators are the perfect solution, especially when space is limited but torque is critical. For example, the A752 actuator packs a punch in a small package. Looking for maximum power? Check out the A4 (single rack) and A42 (dual rack) tie rod actuators – our largest and most robust options.

Multi-position

Multi-position Actuators: Need to rotate between three, four, or even five distinct angular positions? Our versatile multi-position actuators make it easy! While three-position motion is the most popular, we offer four- and five-position options built on the same reliable platforms. For example, our A42 3-position actuator can be enhanced with auxiliary cylinders to achieve those extra positions. Need something more compact? The A032 rotary actuator also comes in a handy 3-position version.

Indexing

Indexing Actuators: Need a simple way to drive an indexing conveyor or rotary table in fixed precise steps? Our indexing actuators deliver unidirectional rotation in fixed precise steps to hard stops, without accumulated error. For the toughest jobs, check out the X42 – our largest and most powerful indexer.

Stepping

Stepping Actuators: Need precise, incremental rotation without the hard stops of an indexer? Our stepping actuators are the answer. They deliver controlled, unidirectional movement in distinct steps, offering flexibility for a wide range of applications. For maximum power and step size, check out the S4, our largest stepper.

P & P

Pick and Place Actuators: Need to master both linear and rotary motion in one compact package? Our Pick and Place actuators are the ultimate solution by combining a rotary section with a linear cylinder, giving you independent control of both movements. Need indexing, stepping, or continuous rotation for your pick-and-place operation? No problem! Our Pick and Place actuators can be customized with any of our rotary motion options.

Nitpicker

Nitpicker Actuators: Like our Pick and Place multi-motion actuators, our Nitpicker actuators combine smooth linear motion with precise indexing for ultimate pick-and-place accuracy. For heavy-duty tasks, check out the PX22, our largest dual-rack model.

Types

The Rotomation product line includes pneumatic and low pressure hydraulic actuators operating at typical pressures of 80 and 250 psi, respectively. All of our actuators, except for the AL75, provide rotary motions generated by a rack and pinion mechanism, in which a piston pushes one of the ends of a gear rack, turning the meshed pinion gear back and forth, depending on which piston is pressurized at the moment.

Our rotary actuators have a one-piece pinion shaft so that back and forth torque is directly transferred to the shaft.

Our stepping actuators deliver torque in a single direction in steps by connecting the pinion to the shaft with a one-way clutch.

With a similar drive mechanism but with precise stopping capability, our indexing actuators produce accurate angular steps using a ratchet and pawl mechanism that provide the solid stop on its shaft.

Pick & place actuators combine rotary motions and linear motions by transmitting rotary torque to a rod in its linear cylinder via a shaft-spline connection.

Features

    In all of our rotary devices, the torque can be doubled by placing an additional rack with pistons and cylinders on the other side of the pinion and arranging plumbing for pressure and exhaust to diagonally opposite cylinders. These dual rack units are designated with a number 2 following the actuator's size or the series' second digit, i.e. 12,22, 32, or 42 (e.g. A22).

    Our miniature or compact actuators are pneumatic but all other actuators can be operated on air or hydraulic oil. In instances where motion control is required, one or more cylinders can be driven by air and the others by oil, through a regulated flow control. Operating conditions and required controls define actuator features to mesh with system control.

    The Rotomation product line includes actuators capable of producing eight motions, which allows them to drive process machines directly, without requiring complex mechanical conversion or driving components.
