Avoid the pitfalls, gain all the benefits of replacing hydraulics with electric actuators

Electric actuators continue to find new and exciting places within automation processes from the mundane to some of the most extreme operating environments on the planet. Everyday machine designers seek alternative electric solutions to hydraulic cylinders for the very first time.  However, there are many common pitfalls to properly sizing an electric equivalent.  When sized correctly, replacement with high-force electric linear actuators can provide tremendous benefit in processes, quality and reducing your total cost of ownership.

Overcoming hydraulic headaches by converting to electric linear motion solutions

Just 20 years ago, users of hydraulic systems struggled to find alternative technologies that could achieve the high force capabilities of hydraulic cylinders.  Since then, motion control and automation technologies have rapidly evolved and electric linear actuator technology has emerged with capability to achieve the high forces (up to 100,000 lbf/445 kN) that were once the sole dominion of hydraulics.  Even with these advancements, many manufacturers are either unaware -- or still in the process of discovering -- that viable electric options exist to address many of the challenges they face with hydraulic systems in high force applications.

Electric high-force linear actuators improve powertrain assembly process and part quality

In automotive and heavy equipment industries machine designers and engineers know part quality and reliability are critical. That is why they often evaluate multiple linear motion technologies (hydraulics, pneumatic, electric) to determine the optimal solution for their component assembly or joining processes. It is imperative for their machines to produce quality parts that stand up to even the most demanding environments in harsh powertrain applications. Luckily, electric linear actuators offer engineers a solution for improving machine flexibility, precision, and reliability where legacy fluid power technologies (pneumatic and hydraulics) often fall short.

For an overview of how electric high-force linear actuators compare to hydraulic cylinders, see our white paper, Electric rod actuators versus hydraulic cylinders: a comparison of the pros and cons of each technology.

Why convert hydraulics to electric high-force linear actuators

Got a high-force linear motion application? If you do, chances are the first product solution to come to mind is hydraulic cylinders. After all, they’re relatively inexpensive (if you already have a hydraulic power unit – HPU – in place), compact (if the HPU’s somewhere else) and power-dense.

But what about the disadvantages of hydraulic cylinders? Leaks, operation and maintenance costs, and more? Now that there are electric high-force linear actuators, machine designers have a choice. It’s possible to convert an application from hydraulic to electric linear motion easily. Our guide, How to convert hydraulic cylinders to an electric actuator alternative, gives you a step-by-step explanation of the process.

Electric high-force linear actuators keep medical manufacturing clean

Machine designers know that hydraulic cylinders offer compact size and excellent power density.  Designers also know there are serious drawbacks that make these cylinders problematic in many applications – problems such as inevitable leaks. Those leaks can be a significant hazard in manufacturing environments that demand cleanliness such as medical equipment production. It used to be that hydraulic cylinders were the only choice when a designer needed a high-force linear actuator. Now there are electric high-force linear actuators that can replace hydraulics in many applications, offering clean operation as well as better accuracy and control.

How to convert high-force linear actuators from hydraulic to electric

Part 2 of 2

Things are changing in industrial automation. Many linear motion applications are getting more sophisticated with increased demand for control of process variables like velocity, thrust, acceleration/ deceleration and more.

It’s common for new applications that require high thrust from a linear actuator to use electric motion systems. Moreover, machine designers are converting existing hydraulic motion systems to electric.

High force linear actuators: how to convert from hydraulic to electric

Part 1 of 2

Electric linear actuators have come a long way – especially in the area of high force.  Once upon a time when an application required high force, the usual linear motion solution was a hydraulic cylinder. However, as industrial automation gets more sophisticated and the need for precise control of speed, force and other variables grows, more engineers are considering electric high force linear actuators.

Changeover is faster with electric high-force linear actuators.

There’s no denying that hydraulic cylinders can provide reliable linear motion in the right applications. However, hydraulics cylinders often leak, and can be difficult to control. When a changeover is needed, adjusting a hydraulic cylinder is a time-consuming, hit-and-miss process. New electric high-force linear actuators are an alternative to hydraulics in many applications.

Electric extreme-force linear actuators beat hydraulics in metal casting

Metal casting is precise work conducted in a high-temperature environment. The process  requires precise control of timing, flow rates and temperatures to yield good parts.

Unmolding a workpiece requires both force and control. It’s a task often left to hydraulic cylinders, but their high-force capabilities come with significant drawbacks, like inadequate control and messy leaks. New, electric extreme-force linear actuators offer precision and clean operation.

Lots more high-force linear actuator solutions with electric

Some machine designers still believe only hydraulic cylinders can handle high-force applications.  But the fact is, electric high-force linear actuators are capable of 30,000 lbf (133 kN) maximum force and more, and they offer great affordability.

Some designers think the selection of electric high-force linear actuators is limited. But the truth is the range of electric high force actuation solutions is always expanding. With this expanding range of solutions, more existing applications can be converted to electric and new applications can gain the benefits of electric actuation.
