What Sets Rotomation Apart from Other Pneumatic Rotary Actuator Manufacturers?
At Rotomation, we specialize in manufacturing high-speed, heavy-duty pneumatic actuators that provide a variety of shaft motions. What distinguishes us in the market is the extreme configurability of our products. This flexibility allows customers to tailor designs to their specific needs, a significant advantage over our competitors. Additionally, we pride ourselves on our ability to deliver custom actuators swiftly and at competitive prices.
Innovative Product Offerings
Our product range includes a standard line of bidirectional rotary actuators, like those offered by competitors, which rotate between two positions. We also offer multi-position rotary actuators that can rotate between three to five positions in any sequence, and multi-motion actuators that combine linear and rotary motions in a single unit.
Unique to our lineup are our unidirectional actuators, available in two families: stepping and indexing. Our indexing actuators, like the popular X4 model, deliver precise and repeatable stops with exceptional non-accumulating error of ±0.2 degrees or less—capabilities unmatched in the market, often serving as more efficient substitutes for servo motors or cam-based drives.
Robust Design and Applications
Our stepping actuators are designed for durability, providing fixed-angle torque without a stopping feature and capable of rotations exceeding 360 degrees. The clutches in these units are integral, with robust shaft bearings ensuring optimal concentricity—a stark contrast to the add-on clutch adapters found in competitor offerings.
The PX2 nitpicker actuator provides both rotary and linear motion, independently controlled, but have indexing rotary motion instead of the back and forth rotary motion as in our pick and place actuators. With the precise indexing action combined with linear motion makes the nitpicker capable of moving parts through a multi-step process using only a single actuator
Compact and Powerful Actuators
Our line of compact actuators, including the high-torque A032 which boasts more torque and bearing capacity than any competitor of similar size, the patented AL75 with its unique soft start and stop action, and the powerful A752, represent the pinnacle of innovation.
Unmatched Quality and Durability
Rotomation actuators exceed industry standards for quality and accuracy. Our products are designed for high-speed operations and are built to withstand harsh environments, making them ideal for a wide range of industries including automotive, semiconductor, food, and pharmaceuticals. Our pinion shafts are made of heat-treated alloy steel for maximum impact strength, and our racks are precision ground high carbon steel, riding in replaceable bronze bearings for long life.
Custom Solutions and Client Satisfaction
Approximately 40% of our actuators are customized to meet specific client needs, whether modifying existing models or creating entirely new designs. Our dedicated team ensures that each actuator not only meets but exceeds customer expectations.
At Rotomation Inc., you gain access to our expert engineering, personalized customer service, and unparalleled technical support—all included with your purchase. When you choose Rotomation, you’re not just buying an actuator; you’re gaining a partner dedicated to your success.
