There are various factors that affect the life of an actuator. As with any industrial tool, the care of an actuator can have a great deal to do with its longevity. Some of the factors that can extend the life of an actuator are:
1.Staying within the rated duty cycle – The duty cycle is a balance between usability and lifespan. The chart below, from Motor Devices, provides an example of a typical duty cycle.
2.Minimize side load – Since actuators are designed to push and pull, side loading significantly reduces how they will be useful. The internal friction caused by side loading rapidly wears out its components. If a side load is necessary, using a slide rail with the actuator will extend its life span.
3.Staying within the recommended voltage – By applying more voltage than is recommended, the actuator will run faster for a short time but will wear out quicker.
4.Force – Actuator has a defined load capacity, such as 20 pounds. Operating it below its designed maximum capacity will extend its life.
5.Extreme environments – Though most actuators are designed to operate in industrial environments, it is best to avoid extreme heat, cold, dirt or dust, and moisture. There are actuators that are designed to operate underwater and may be a choice for damp or moist conditions. The actuator below, from FB, is designed for underwater use.
