Making the case: Why convert a tube-bending machine from hydraulic to electric

Tube-bending machines have been driven by hydraulics for the past 80 years. Operators know how to get the best out of their machines, so why switch to electric cylinders? Yes, there are some disadvantages to going electric, but the fundamental reason to consider making the switch is simple: Electric cylinders make better parts. And that saves money. We'll discuss reasons to consider making the switch and take a look at two examples using electric-weld tubing and fluid-transfer tubing.

High-force linear actuators. Roller screws vs. ball screws

Not too long ago the only solution for high-thrust linear motion was fluid-powered cylinders that used high-pressure air or hydraulic oil. Although these cylinders could provide the force required, they could not deliver on requirements for infinite positioning, speed control, and low maintenance.

Now there are electric rod actuators that deliver high forces and excel at the other criteria as well. Often these electric high-force linear actuators utilize ball or roller screws. However, it’s a challenge to choose the right screw technology for a high-force application.

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.

Converting From Hydraulic to Electric High-Force Linear Actuators with Force Feedback

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.

High force linear actuators: How to convert from hydraulics to electric

For high force linear actuator applications, machine designers often first look to hydraulic cylinders. For good reason, too – hydraulic cylinders can be a bargain to purchase, delivering high force at a low cost per unit of force.  Plus, they’re rugged and well understood. But there’s another technology to consider. Electric linear actuators are available with high force capacities.  These actuators are more flexible, precise and reliable than their hydraulic counterparts.

Electric high force linear actuator is tough enough to process lumber

The lumber industry has relied on the toughness and high force capabilities of hydraulic cylinders for years.  But lately that reliance has been shaken.  Hydraulic cylinders leak and can contaminate the fragile eco-systems in which lumber processing operates.  Plus, hydraulic systems are only 40-55% efficient and cylinders require frequent maintenance.  When combined, these factors can make hydraulic cylinders an expensive choice in the long run.

The introduction of electric high force linear actuators has given the lumber industry a new option for linear motion.

Hydraulic vs high force electric linear actuators: new infographic

Choosing the best linear actuator for a task takes a thorough understanding of the application. The basics like the weight of the load, the distance the load’s to be moved, and the speed and force needed are all important factors. A machine designer may also need to consider variables like environmental conditions, data collection and reporting,  as well as flexibility/programmability requirements.

If the application calls for a high force linear actuator, the usual solution has been a hydraulic cylinder. However, high force electric linear actuators are now available  (many with roller screws) and offer distinct advantages. Our new infographic compares the performance of electric, hydraulic and servohydraulic actuators on intelligence and operational parameters.

Hydraulic linear actuator advantages and disadvantages

Hydraulic cylinders are popular automation components in many industries. Like other types of linear actuator (pneumatic and electric), they are used to move loads in a straight line. A hydraulic actuator uses the energy in a pressurized liquid, usually oil, to achieve this linear motion, as opposed to compressed air (pneumatics) or electricity.
