Rotary Actuators

Rotary actuator motion symbol

Basic rotary actuators provide back and forth rotation between two positions. All Rotomation rotary actuators feature black-anodized aluminum bodies, one-piece heat-treated alloy steel pinion shafts, ball bearings, and stainless steel or black-oxide alloy steel hardware.

Common Options: adjustable rotation, various shafts and keyway orientation, bumpers, magnetic switches for position feedback, and various port locations.

Compact Rotary Actuator Group Compact Rotary Actuators

Rotomation's compact rotary actuators are designed for applications where high torque in a small space is important. Their unitized construction minimizes space requirement and provides a clean appearance. All common options are available, and some also have cushions, washdown protection, and metric shafts sizes available. Standard and special rotations up to 190 degrees are available. A032 and A752 are dual rack actuators, eliminating lash (free rotary play of the shaft) at the end of rotation.

Single rack Tie Rod Rotary Actuator Group Single Rack Tie Rod Rotary Actuators

Tie rod construction offers maximum configurability and durability, and are fully rebuildable. Single rack actuators are designed for general applications where reliability and durability are important and where a small amount of lash (free rotary play of the shaft) is tolerable. All common options are available and also hollow shafts, integrated cushions or flow controls, washdown protection, high temperature or hydraulic seals, high-cycle construction. Fifteen standard rotations, from 30 to 730°, and special rotations available up to 1,080°.

Dual rack Tie Rod Rotary Actuator Group Dual Rack Tie Rod Rotary Actuators

Dual rack actuators have the additional advantages of double torque and zero lash at the ends of the rotation without increasing the footprint of the actuator. All construction features and options available on single rack tie rod actuators are also available on dual rack actuators.

 

 ROTOMATION NEWS!

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 from corrosive materials. The new actuator and gripper grips the bottle; rotates it to the desired degrees for filling, then rotates back to release the bottle.
