Product Spotlight: Helac Rotary Actuators

Reading Time: 3 minutes

The physics of machines is deeply defined by many scientific principles. Energy cannot be created or destroyed; it simply changes form. This statement is particularly true when it comes to rotary actuators in manufacturing and other industrial applications.

These components make it possible to move machines in unique trajectories on a regular basis. Get to know rotary actuators, including the types made by Helac. Your industry benefits from structurally sound actuators applied in the proper locations.

What are Rotary Actuators?

Rotary actuators are devices that convert linear energy into rotational motion. Most machines require some sort of rotational energy. You’ll find rotary actuators in these applications, such as:

  • Valve operations
  • Steering applications
  • Positioning and tilting
  • Conveyor switching

At any Parker Store, you’ll find several Helac models that work for specific applications. For example, choose an L10 series rotary actuator when you need moderate work to be completed. Heavy-duty applications often require an L30 or T20 series model. Understanding the science behind rotary actuators will give you a deeper knowledge about the world of rotational motion.

Basic Design

There are many variations on rotary-actuator design. However, there are two models that tend to define the industry. These designs include:

  • Vane
  • Rack and pinion

You might be shopping for fittings at our Parker Stores, but you also need the best design for a broken-down actuator. A vane design uses a shaft attached to a perpendicular length.

Pressure against the length or vane causes it to rotate to a certain position. As it finishes its movement, pressure from the opposite side forces it to move back to the original position.

Rack-and-pinion designs use a gear rack with a shaft connected to it. Pressure forces the shaft to move as the gears engage.

Picking Out Torque Specifications

When it comes to picking out parts, from rotary actuators to Parker fittings, torque is an important feature. Helac offers the L20 series of actuators with a maximum drive torque of 39,000 in-lb. of force, for instance.

You’ll need to match your application to the required torque. Ideally, you don’t want to reach these maximum values on a regular basis. Your system should reach the middle point of the actuator’s abilities. This sizing strategy prolongs the component’s lifespan.

Defining the Pressurized Materials

Whether you’re purchasing a rotary actuator or Parker hose, you must know how the system works to match the proper parts. Rotary actuators can be powered by:

  • Electricity
  • Hydraulic fluid
  • Air

Each one of these substances performs a specific task for a system. For instance, construction machines often use hydraulic fluid for their needs. Manufacturing machines, in contrast, might opt for electricity to create a steady stream of parts. An expert at a Parker store can help you pick out a rotary actuator for your particular industry.

Repeatable Positioning

When you place a rotary actuator into service, you want to know that it’s reliable. In other words, it must be repeatable when it comes to positioning.

You’ve just installed a basket on a hydraulic crane. Along with a Parker hose installation, this actuator addition must tilt and hold the basket in a proper position. Helac’s entire line of rotary actuators have incredible repeatability, which includes the rack-and-pinion design. Complex engineering makes every Helac actuator a reliable part for those busy days in the field.

Mounting Considerations

Helac products also give you versatility when it comes to mounting the actuators. Choose from these mounting locations, such as:

  • Flange
  • Foot

Regardless of our 28 locations that you might visit, we can determine the best positioning of a new, Helac actuator at your site. There’s a solution with either the L or T series installed in various industries.

The world of rotary actuators may be difficult to traverse, but there are experts who can show you the way. Reach out to our team to verify your application and material needs. Understanding your machine’s components will only improve your business’s productivity and bottom line.
