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.

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.

Electric high force linear actuators with roller screws rival hydraulic

When you’re specifying a high force linear actuator, your application’s requirements call the shots. It used to be that hydraulic cylinders were your only recourse when high force was needed.  Now there are electric linear actuators with roller screws that rival the high force, high thrust, high torque capabilities of hydraulics.  Plus, these electric actuators deliver high speed, great accuracy and repeatability and long life. Electric roller screw actuators are definitely an alternative to consider.

High force linear actuator: electric replaces hydraulic

It used to be that when a machine designer was confronted with a high force linear actuator application, the only solution was a hydraulic cylinder.  That meant the designer had to factor in the bulky hydraulic power unit (HPU), the inevitable leaks of hydraulic fluid and the downtime produced by frequent maintenance.

Now there’s another option when a high force linear actuator is needed. There are electric linear actuator products that can meet demanding specifications with ease.

High force linear actuators: hydraulic vs roller screw actuators

How to select the best high force linear actuator for your application

Hydraulic cylinders have long been a leading choice for factory automation equipment needing a high force linear actuator. However, there have been advances in electric actuation (for example, the availability of roller screw actuators) which make these electric actuators suitable now for many high force applications.

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.
