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.

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.
