How to select electric linear actuators that stand the test of time

The length of time a linear actuator will function (i.e., service life) is critically important to a machine designer. Machines need to keep working reliably with little or no need for lengthy maintenance that will take a machine off-line . So, components like actuators must keep working.

Go long! Selecting a long stroke electric linear actuator

Some linear actuator application requirements mean you have to go long. Long stroke, that is. Length of stroke is a critical factor in electric linear actuator selection. While some applications require moves of just inches or a few feet, others require moves of 10 feet or more. For an application requiring this kind of long stroke linear actuator, a belt driven rodless electromechanical actuator will be your solution.

Integrated servo motor/controller/drive saves cost and plant space

Space is at a premium in most manufacturing operations. And of course, saving money is a constant goal. Plant managers are looking for ways to save money and space, so machine designers are tasked with creating ever more compact, affordable systems.

A new class of products addresses the needs for lower cost and efficient use of space: the integrated servo motor/controller/drive. These systems combine a servo motor and controller with a servo drive. They’re compact and eliminate the need for a drive cabinet.

Machine design, clean in place (CIP) and linear actuators

Keeping clean is important, right?  Well, in food and beverage processing and pharmaceuticals manufacturing keeping equipment clean is essential.  Cross-contamination among batches causes problems, and food or beverage residue can grow harmful microorganisms. Many plants have clean in place (CIP) systems that deliver cleaning tailored to the needs of the facility including cleaning action (force, turbulence, direction), timing/duration (when, how often, how long), temperature, and type/strength of cleaning agent.

When you design equipment for these industries you need to keep cleanability in mind.   Even components like electric linear actuators must stand up to cleaning procedures.

Ball and roller screw linear actuators: How to compare service life

When you’re designing equipment, you'll probably be asked, “How long will this machine last?” And even if you’re not asked outright, you know service life is an essential consideration. It’s a critical factor you consider when sourcing components.

Electric linear actuators are important components in many machines, and the “how long will it last” question is a familiar one. If it’s a ball or roller screw actuator, you can use a formula to help estimate life based on load – the same formula used to estimate bearing life.

Electric linear actuator ebook: A resource

Industrial automation counts on the reliable motion control that linear actuators provide. Lately, electric linear actuators have gotten more popular because they offer better control of variables like speed, acceleration, position and force than pneumatic or hydraulic cylinders. Electric actuators also offer superior accuracy and repeatability, as well as programmable control that can handle even complex motion profiles.  In many applications, they can do all this at a lower cost of ownership than pneumatic or hydraulic actuators.

Choosing the right linear actuator [INFOGRAPHIC]

When your design calls for a linear actuator, you have lots of choices.  Pneumatic, electric, rodless, rod, belt driven, screw driven. These are just some of the options available.

Electric linear actuator accuracy and repeatability webinar

When an engineer is developing a machine design, accuracy is often top-of-mind.  So is machine cost. But these two considerations can be at odds since the usual scenario is that the higher the accuracy of a device, the higher the cost. This certainly holds true for electric linear actuators and linear motion systems.

Electric actuator life in units of time: ball & roller screw actuators

A machine’s useful life depends on the life of its critical components. And machine designers  frequently hear the question, “How long can I expect this machine to keep working?”

When electric linear actuators are used, calculating life can be straight-forward for ball screw and roller screw actuators.  Since these screw types incorporate rolling elements as essential parts, you can use the L10 life formula for ball bearings.

Selecting a rodless electromechanical actuator: belt- vs. screw-driven

Let’s say you’ve decided you need a rodless electromechanical actuator to carry a load in your application. Now you have to select a linear drive system. The two most common choices are screw drives and belt drives. Both drive types offer long life, low maintenance, and efficiency in converting the motor’s rotary motion to the carrier’s linear motion. However, each drive type is more suited to particular applications than others, depending on a few key factors.
