Linear actuators combine mechanical engineering, electronics, computer engineering, systems engineering, and control engineering to improve and optimize product design and manufacturing processes. Generally, there are two types of linear actuators.
The first type of linear actuator, often called a rod-style actuator, typically is round and has a screw in the middle of the moving element. This element or rod extends out the end of the cylinder and retracts back into the cylinder in a linear fashion. These types of actuators are typically only used in single axis applications.
The second type of actuator is built around either a square or rectangular structure of some sort, that encloses the drive or force transfer mechanism (screw, belt, etc.). This drive mechanism is attached to a carriage which is supported by some type of bearing system that guides the linear motion. PBC Linear specifically manufactures this type of electric linear actuator with a range of drive options that can be powered either by a hand crank or motor. These types of systems can easily be configured for multiple X-Y-Z applications.
There are four main types of linear actuators: hydraulic, pneumatic, electric, and mechanical. Hydraulic linear actuators rely on compressed fluid for movement while compressed air powers pneumatic actuators. PBC Linear specializes in electric and mechanical linear actuators meaning our actuators are driven by lead screws, ball screws, and belt drives as well as options for motor driven systems.
We offer a variety of carriage types, drive components and motor options so customers can customize the linear actuator solution that is best suited for their linear motion application.

Every linear actuator is a device which converts some type of rotary force and applies it to achieve an in-line or linear movement. This force could be coming from a hand crank or electric motor transferred through some type of screw for example. This motion can be used to move, position, or control various mechanical systems in applications ranging from industrial machinery to medical equipment.
Linear actuators are advanced systems built with high-precision components and a durable design, making them ideal for heavy-duty applications. Their superior technology and engineering contribute to the higher cost, but they offer significant value. Most linear actuators are ready to use right out of the box, requiring minimal modifications, which helps reduce downtime and saves on installation costs, providing a seamless, plug-and-play solution for customers.
In addition to complete linear actuator systems, PBC Linear also offers lead screw and ball screw driven servo motors. These lower cost options are excellent alternatives for applications that may require less precision.
PBC Linear provides nine distinct families of linear actuators, each designed to excel in handling various loads, strokes, and operating environments. For example, our Simplicity® Linear Actuators can accommodate carriage loads up to an impressive 83,000 N (18,750 lbf), making them ideal for demanding applications where reliability and strength are critical.
Combining the mechanical, electrical, and control elements of engineering creates a simplified design that is flexible and more user friendly. A one-unit, compact design reduces the number of components as well as space needed for installation. Less components means less labor invested, reduced time spent in setup and maintenance, and maximized operational uptime.
In a variety of situations, linear actuators have proven to be a more reliable solution due to their enhanced features and functionality. For example, in the internet of things (IoT), linear actuators provide the following benefits:
Combining various engineering subfields into the same design not only makes it safer, more efficient, and cost effective. Examples of efficiency and cost effectiveness of mechatronics in an IoT environment include:
There are several factors to consider when designing a linear actuator into a linear motion application. When designing a system with linear actuators, consider these key elements to ensure optimal performance:
