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.

Extreme force electric linear actuator controls lumber drying

The lumber processing industry demands rugged, strong, reliable and accurate equipment in all its operations. Machine designers who serve this industry need extreme force linear actuators to move heavy loads.  Hydraulic cylinders have been the go-to, but they have limitations, such as poor control, leaks, temperature sensitivity, maintenance requirements and lack of feedback. Now there are electric rod actuators powered by roller screws that can meet the requirements of these high force applications.

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.

High force linear actuators – hydraulic vs electric [WEBINAR]

When your application calls for a high force linear actuator, you may believe that your only choice is a hydraulic cylinder.  Hydraulics have long been the leading choice for automation equipment needing high force. However, now there are electric high force linear actuators  that offer important advantages over hydraulics in terms of performance and total cost of ownership.  Watch this webinar, and you may want to reconsider the merits of using an electric rod actuator.

Which is best for high force linear actuators: Ball or roller screws?

If you’re selecting an electric high force linear actuator, you may believe you know the answer to the question in the headline.  The force transmission prowess of roller screws is well known.  But before you go to the expense of a roller screw linear actuator, take a careful look at the application.  You may find that a ball screw actuator will do the job.  And that could mean significant savings.

Acme, ball and roller screws for electric linear actuators

When you’re specifying a screw-driven electric linear actuator, you’ll need to consider the type of screw that best meets the needs of your specific application. Some manufacturers give you a choice so you can tailor the device precisely, and that’s a good thing since applications differ widely.

The basic types you’ll have to choose from are roller screws, ball screws and acme screws.  There’s quite a lot a machine designer needs to know about these electric actuator screw types and how to select the right one.  We offer a guide that helps your decision-making.

Corrosion resistant integrated linear servo actuator is high force

The electric rod actuator is an industrial workhorse, one you’ll find in a wide range of machine tool, conveying and positioning applications.  A familiar mechanism, yes. But identifying one that’s compact, corrosion resistant and can deliver high force is a tall order. A corrosion resistant integrated linear servo actuator can be the answer.
