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.
