Failure not an option? How to avoid premature linear screw actuator failure

Some components are more mission-critical than others.  A main worry of machine design engineers is making equipment that will last and avoiding need for field service calls to diagnose issues and replace failing components.  At their core, electric linear screw actuators deploy mechanical technology such as ball bearings, ball screws and roller screws that have a finite life.  These components do not last forever, even though that is the expectation of some customers.  When asked “How long will this actuator last?” we provide our customers with a way to calculate, estimate and size the electric linear screw actuator to achieve the desired life for their applications.

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.
