What is a linear actuator used for?
A linear actuator is used to move a load along a straight trajectory. Compared to linear guides, linear actuators are more complex systems that already include the drive (belt, ball screw or rack and pinion). Linear actuators can be combined to combine two- or three-axis cartesian robots. These components are used in a wide range of industrial and mechanical applications.
Linear actuators are essential components in industrial automation, where they ensure precise and repeatable movements. These systems are suitable for many industries, including packaging, industrial machinery and logistics for example, thanks to their versatility and reliability even in harsh environments.
How to choose a linear actuator?
The choice of a linear actuator depends on several factors related to the requirements of the application in which the linear actuator will be used. One of the criteria to consider is the load, i.e. the weight that the actuator will have to move. Another relevant factor are the dynamics: speed and acceleration. Finally, for many applications, the first criteria to consider is accuracy in terms of positioning repeatability.
How many types of actuator are there?
Rollon offers a wide range of linear actuators, each suited to specific application requirements. Belt-driven linear actuators are ideal when speeds and accelerations are required.
Ball screw actuators, on the other hand, offer excellent precision and repeatability. They are particularly suited to applications requiring accurate and repeatable movements, ideal for contexts where precision is essential.
Finally, actuators with rack and pinion are perfect for applications requiring movement over long distances, while maintaining rigidity and precision.
