  • They Day I Learned About Linear Actuators and DVD Players

    Recently we discovered that one of our prized possessions, our DVD player, was no longer working properly. We were not exactly sure what the problem was because we could not get the tray into which you place the DVD to play it to open. The machine seemed to be locked up. We did a little bit of research, which consisted of us prying the tray open and not being able to close it up again, and then went to the internet for help. We discovered that the source of the...

  • Actuators: Driving Lean Manufacturing

    In the industrial world, few concepts are catching on as quickly as lean manufacturing. I constantly read and hear on blogs and radio shows about the importance of leanness as industry works to right itself in the wake of the financial crisis. At the heart of lean manufacturing is waste reduction. In modern industry, waste reduction often involves automation. Automation depends on actuators. I suppose one could say, then, that if lean manufacturing is helping to make industry stronger, one could also say that linear actuators are helping to make...

  • Rotary Linear Actuators

    Not all actuators are used to produce linear motion. Granted, the word actuator, within the context of industry, tends to be associated more often with linear motion than with other kinds of motion. But rotary actuators are important tools for industry, and they serve a variety of purposes in a variety of contexts. Also, in addition to their capacity to actuate rotary motion, rotary actuators can actually be used to generate linear motion in situations in which traditional linear actuators are not appropriate. Let's start with some of the linear...

  • Moving Forward with Linear Actuators

    by Joanna Dykhuis, IQS Editor Kitchen automation has little to do with robots, conveyor belts or self-assembling food, contrary to the images that pop up in my head immediately upon hearing the phrase. We live in an electronic-filled world with new gadgets being developed all the time. It only makes sense that technology would eventually make it to the kitchen. Linear actuators are the devices mainly responsible for the introduction of popup spice racks or fold-down televisions. Though appliances such as microwaves, refrigerators and dishwashers have drastically improved through new...

Industry Information

Rotary Actuators

Rotary actuators are compact, simple and efficient linear actuators that rotate an output shaft through a fixed arc to produce oscillating power. They require limited space and simple mountings and can produce high instant torque in either direction. Rotary actuators are used for lifting, lowering, opening, closing, indexing and transferring movements.

The various forms of energy that run rotary actuators include hydraulic, pneumatic, and electrical. Hydraulic rotary actuators are often used for steering or as an alternative to hydraulic cylinders or motors. Pneumatic rotary actuators are commonly used for material handling, product assembly, testing and quality control, packing, welding, and machine loading and unloading applications. Lastly, for electric rotary actuators, there is a wide range of application including automotive power lock systems, fertilizer spreaders for farming and wind turbine construction. In addition, there are several important factors to consider upon selection of a electric rotary actuator for a desired application, including actuator torque, range of motion and design. For instance, the two main types of rotary actuator designs are rack and pinion style and vane style, although a combination of these two styles is also possible.

The basic method through which rotary actuators provide rotary motion is through the rotation of an output shaft through a fixed arc. However, the three main types of rotary actuators each have different constructions. Hydraulic rotary actuators use pressurized fluid to turn motorized components. Either a circular shaft or a table can be used as the rotational element. Hydraulic rotary actuators are faster and stronger than pneumatic rotary actuators. Pneumatic rotary actuators use pressurized air to turn motorized components. Types of pneumatic rotary actuators include single rotary vane devices, double rotary vane devices, multi-motion rotary vane actuators, single rack-and-pinion actuators, and double or four piston rack-and-pinion actuators. Electric rotary actuators rotate from open to close using butterfly, ball, and plug valves. With the use of electric rotary actuators, the electromagnetic power from the motor causes the components to rotate, allowing for numerous stops during each stroke. Either a circular shaft or a table can be used as the rotational element. When selecting a rotary electric actuator, important factors to consider include the power that causes the rotation, while the full range of motion can be either nominal, quarter-turn, or multi-turn.
