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.
