Small linear actuators are used for robots, motion-enabled products, and automatic valve products. Size and weight are important factors to consider, as well as force and speed. Small actuators are useful for keeping robots small and can fit more hardware. The force of small actuators is typically between 400 and 2,000 pounds, and their speed rating is usually 20 to 40 inches.
Small linear actuators, also known as micro linear actuators, are devices that use a motor to push an object back and forth; they are frequently used for robots, motion-enabled products, and automatic valve products. Size is an important factor for a small linear actuator because most users get smaller actuators to fit in a given space. Along with size, weight is often an issue, because smaller actuators have lower weight, which may be necessary for some products. The small linear actuator typically does not have the same force as a large actuator, so users should verify that the force is sufficient for the application. Speed is another aspect to consider, as the actuator will need to move fast enough to accurately complete the task.
When a user decides to purchase a small linear actuator, size is one of the main considerations. Small linear actuators do not have an official size that qualifies a linear actuator as “small” and some are smaller than others. This is especially important in fields like robotics, where a small actuator helps keep the entire robot small and makes it easier to create the internal components, because more hardware can fit into a small actuator than a large one.
While size is very important, the weight of the small linear actuator must also be considered. Heavy wall mounted actuators, such as curtain actuators, can fall off their mounting point if they are too heavy. This is also important because excess weight can reduce the usefulness of the device or make it completely useless.
A small linear actuator does not have the same motor as a full size linear actuator, so many smaller models cannot replicate the amount of force available from a full size actuator. For this reason, and because force is important in many experiments and applications, users should control the amount of force the small actuator can produce. The typical amount of force for these actuators is between 400 and 2,000 pounds (181.4-907.1 kilograms).
In addition to providing adequate force, a small linear actuator must also be able to move quickly enough to satisfy the experiment or application. These smaller actuators are lighter than full-size actuators, so they typically don’t sacrifice much speed. Most small actuators have a speed rating of 20 to 40 inches (50.8 to 101.6 centimeters), which should be sufficient for general purpose applications, but some high speed applications may require faster actuators.
