How to calculate electric linear actuator service life

 Every machine design engineer gets asked about the anticipated life of their machine—life that’s based on machine components including electric linear actuators. Also, expected service life is a factor engineers consider when they’re evaluating competing components.

Calculating electric linear actuator life can be straight-forward for ball screw and roller screw actuators. You use the L10 life formula for ball bearings. Here's a summary of the method.

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.
