To differentiate between linear or rotary actuators, consider their motion profile. In the case of linear actuators, they generate push or pull movement along a straight line through rotary motion. Different types of linear actuators utilize energy sources such as electricity, pressurized hydraulic fluid, and compressed air or gas to power the motor that creates that rotary motion.
Operators have control over the speed of actuator movement, ensuring safe and efficient processing with high repeatability and positioning precision. Industries from aerospace and defense to agriculture and food and beverage make use of linear actuators for their cost-effectiveness and versatility in wide-ranging automation applications.
Different Types of Linear Actuators
To best suit the needs of these varied industries, engineers have developed three main types of actuators: mechanical/electromechanical, hydraulic, and pneumatic.
Mechanical and Electromechanical Linear Actuators
An external force activates a mechanical linear actuator, and an internal force for electromechanical linear actuators, but both derive linear motion by converting rotary motion. A motor such as a servo, a stepper, or a gearmotor utilizing AC or DC power typically fuels electromechanical linear actuators. Among electromechanical actuators, you’ll frequently find ball-screw, roller-screw (also known as planetary screws), or lead-screw designs. All three contain a rotating nut that moves linearly along a screw shaft. Using these actuators can provide more control over distance and force, though they are typically more expensive than other types.
Hydraulic Linear Actuators
Rather than an electric signal or manual motion, hydraulic linear actuators gain power from oil or other pressurized hydraulic fluid. You’ll find these in operation in machines and equipment situated in rugged environments and terrain, such as construction sites or mining excavations. Hydraulic linear actuators are ideal for high-force and high-power applications, especially where you require shock load capacity and consistent pressure. However, these actuators need a lot of power, often suffer from leakages, and are quite noisy. You can also damage hydraulic actuators if you operate them at high temperatures, and they require added parts for full functionality.
Pneumatic Linear Actuators
Pneumatic linear actuators convert compressed air or gas energy to produce straight motion. Speed and cost are the primary benefits of these actuators. They’re reliable and effective for applications that require the rate of linear motion in objects to be up to 60 inches per second. However, you’ll also need a compressor, which generates noise during operation, and pressure losses disqualify these actuators from applications needing absolute movement precision.
Features of Linear Actuators
Linear actuators have enjoyed widespread usage because of their reliability and versatility. Actuators pair with various power sources and come in numerous design configurations, such as screw, rod, or belt type, that provide the requisite force, precision, and acceleration/deceleration speed for multiple applications.
Requiring very little operator maintenance, actuators can have a long working life. You can deploy them in harsh environments, and they still provide high repetition, accurate positioning, and precision movements. Depending on the type you use, linear actuators can also be quite compact.
Industries and Applications for Linear Actuators
You will find linear actuators in many industries. Some of the most common are:
- Clean and renewable energy
- Food and beverage
Actuators are critical components in many processes within these industries. For example, actuators capture and harness solar, tidal, and wind energy to power equipment and buildings. You can find them in automotive features ranging from power liftgates to sunroofs. Tanks use actuators to elevate their weapons systems. Also, factories in numerous industrial sectors use actuators to operate conveyor belts, robots, and other automated equipment.

Actuators are mechanical devices that convert energy into motion. These components are incorporated into a wide variety of products, from industrial equipment to household electronics. The energy source of an actuator can be electric, hydraulic, or pneumatic power.
High-quality, heavy-duty actuators are critical for industrial operations, where they are responsible for facilitating linear and rotary motion to convey materials and operate equipment. For heavy-duty operations, ball screw actuators and roller screw actuators are ideal. We will explain the characteristics, benefits, and differences between ball screw and roller screw actuators so you can choose the one that best suits your needs.
Ball Screw Actuators
Ball screw actuators convert rotary motion to linear motion. They feature a nut mounted on a grooved screw shaft. Inside the nut, recirculating balls roll within the groves of the screw shaft. As the screw turns, the nut moves up and down the shaft along the grooves, creating linear motion that can be finely controlled by turning the screw. Ball screw actuators provide precise control for medium-duty to heavy load-bearing applications and can accommodate high-speed processes.
Ball Screw Applications
Ball screw actuators provide smooth, energy-efficient motion with exceptional accuracy and precision control. They offer continuous high-speed, high-force movement for long periods of time. These benefits make ball screws ideal for:
- Wind turbines
- Solar panels
- Vehicle power steering
- Assembly equipment
Roller Screw Actuators
Roller screws have a similar construction to ball screws, but instead of recirculating balls, they contain rollers that are threaded to match the threads on the main screw shaft. Since the rollers do not touch each other, they do not interfere with each other’s motion and can operate significantly faster than ball screws. The individual rollers have greater surface area contact with the main shaft than recirculating balls, so they have higher axial load characteristics, higher dynamic load capabilities and thus longer life than comparable ball screws. They also generate more heat and require more lubrication at tighter intervals.
Roller Screw Applications
Roller screws can withstand high force and repetitive motions for long periods of time. They can be controlled with a high degree of precision, and their extensive surface area provides additional stress dispersion in high-force applications, such as:
- Automotive and aerospace manufacturing
- Metal casting and molding
- Paint spraying
- Pressing, inserting, and riveting
- Precision CNC machining
- Automated, high-speed manufacturing equipment
Which Actuator Is Right for You?
Ball and roller screws each offer unique advantages for different applications. To determine which actuator is ideal for your needs, consider the following:
- Operational Life: In general, roller screws have a longer service life and offer good ROI when operated for extended periods of time. For projects lasting less than three years, ball screws are highly effective and make an excellent investment. Depending on the budget and length of your project, ball screws may be ideal for short-term, low-budget projects, while roller screws would be better for long-term applications.
- Expected Force: Longevity is greatly affected by the amount of force exerted. Roller screws are better than ball screws for heavy loads over eight tons. For applications with lower load capacity, balls screws represent an excellent low-cost option.
- Maintenance Frequency: Due to the amount of friction and heat they generate, roller screws often require more lubricant and maintenance than ball screws, especially in high-speed operations. Both types of actuators operate best with sufficient lubrication and regular preventative maintenance.
- Contact Area: Due to the lack of contact between rollers and the bearing, roller screws transmit more force more quickly. Ball screws must make contact between balls and the bearing, so this can interfere with ball motion, reducing efficiency and increasing wear on the actuator elements.
- Cost: Ball screw actuators are significantly less expensive to obtain, maintain, and repair. Components are readily available open-market, and their simple design makes them easy to fix. Roller screws, on the other hand, are more complex and contain more specialized components, which makes parts harder to source and more expensive to repair or replace.

Actuators are mechanical devices that use energy to generate motion. Manual or automatic control commands initiate change in physical systems, creating motion to perform a task. Actuators allow machines to lift, block, clamp, eject and more.
Depending on the type of energy source used to produce motion, three main types of actuators are available: hydraulic, pneumatic and electric. Below we’ll review the characteristics of these actuators as well as their applications and advantages.
Known as the most commonly used energy conversion system, hydraulic actuators are an especially popular choice for systems requiring high-force automation equipment. These actuators rely on oil fluid compression.
A variety of heavy-duty applications use hydraulic actuators to produce anywhere from ½ to 4,000 tons of force. These potential applications include:
- Cargo handling
- Large construction equipment
- Military weapons
- Marine propulsion
- Transportation systems
Advantages of Hydraulic Actuators
Hydraulic actuators bring the following benefits to an operation:
- Good strength-to-weight ratio: Hydraulic actuators can deliver tremendous force relative to their weight.
- Safety: They include various safety features, including rod locks, dump valves that quickly dissipate energy, and bypass valves that close off high-pressure oil when generating motion.
- Mobility: Hydraulic actuators are also compact enough to take on mobile operations, servicing trucks and other heavy transportation equipment.
Most pneumatic actuators feature compression rates of 80 to 100 psi, making them a more stable and safe option for applications requiring less force. These actuators capture atmospheric air and compress it at higher pressures to generate motion. The specific parts of a pneumatic actuator include the actuator, storage tank, system of delivery hoses, motor and compressor unit.
Advantages of Pneumatic Actuators
The benefits of pneumatic actuators include:
- Speed: The fastest actuators are pneumatic. Fast cycle rates contribute to greater productivity and profit.
- Cost effectiveness: Pneumatic actuators have lower upfront costs compared to other actuators. They return their initial investment quickly, especially for moderate-duty applications.
- Simplicity: Pneumatic actuators are relatively simple, so they are less likely to malfunction and easier to repair if they do.
Electric actuators use a motor to convert electric energy into torque, producing motion. They use a variety of mechanical components—gears, planetary roller screws, ball screws, lead screws—to generate linear energy from rotational energy.
Small electric actuators are best for low- to medium-duty applications, such as packaging, factory robotics, automotive manufacturing and medical devices. Large electric actuators can produce up to 50,000 lbs of force.
Advantages of Electric Actuators
Electric actuators provide the following main benefits:
- Speed: Electric actuators respond quickly to generate motion, with speeds of up to 20 in./sec.
- Precision: Unlike hydraulic and pneumatic actuators, electric actuators are highly precise because they are not subject to inherent tolerances.
- Cleanliness: Electric actuators use electricity, a clean energy source, eliminating the risk of leaks.

Actuators are designed to convert energy from different sources, such as electric currents, pneumatic pressure, or hydraulic fluid pressure, into motion. There are three main types of actuators: pneumatic actuators, hydraulic actuators, and servo actuators.
Servo actuators use feedback signals to move or control mechanical systems in a highly efficient and safe manner. This is possible because servo actuators have a controller that can accurately compare, contrast, and calculate the potential differences between the desired results and system conditions on a real-time basis before the motion starts.
Servo actuators use a servo motor in either an open or closed-loop control system. Several servo actuator models have a food-grade approved coating of paint for more sanitary wash-down applications.
Servo actuators are available in both ball and roller screw configurations, like the HyperCyl-EMA, which has several options available for output force. They have an extended service life because they can easily be re-lubricated without disassembly.
How Does a Servo Actuator Work?
A servo system has three main core components:
- A controlled device that allows the actuator to successfully operate
- An output sensor/signal that acts as the main controller to tell the device what to do
- A position sensor, encoder feedback, or load cell to provide accurate system feedback readings
Servo Actuator Control Systems
The control systems, which allow the actuators to operate, come in two different designs.
Closed-Loop Control System
Commonly referred to as feedback controllers, this type of control system is fully automatic and uses the input of the system and the output of the system controls to function. Closed-loop control systems are usually very accurate.
Open-Loop Control System
Commonly referred to as a non-feedback system, this type of control system is not automatic and doesn’t have a feedback loop. The output of the system depends on the input. However, the input or controller is independent of the output produced by the system. Open-loop systems do not measure the device’s output or use the information as input for further consideration.
How Do Servo Actuator Controls Work?
Servo actuators are controlled by a feedback signal generated by comparing the output signal and the reference-input signal rather than a variable-input signal. Whenever a command or reference-input signal is applied to the system, it is immediately compared with the system’s output-reference signal produced by the output sensor. Lastly, a third signal is produced by the servo actuator’s feedback system before it starts to move.
The device can also be programmed with certain instructions and autonomously perform the movements on its own. For example, the actuator can receive a command to go to a specific position and immediately follow the command. This makes them very different from comparable pneumatic valves (pneumatic actuators) and pumps (hydraulic actuators), which can only follow simple instructions to ‘power on’ or ‘power off’ on their own.
Applications of Servo Actuators
There are numerous applications of servo actuators. Some of these include toys, home electronics, computers, drones, and remote controlled cars.
Servo actuators also often play a crucial role in the function of both land- and sea-based vehicles – such as automobiles, airplanes, helicopters, and submarines.
Servo actuators can contribute to the function of these parts in automobiles:
- Engine Cradle Assembly
- Engine Sub-Assembly
- Ball Joints and Bushings
Airplanes and Helicopters
Servo actuators adjust the wing angle of airplanes and control steering by moving the levers back and forth. Airplanes can easily “fly-by-wire” when they have a servo-controlled main system instead of an older hydraulic-powered one.
Servo actuators can also control the speed of a helicopter by moving a swash plate, which can tilt the pitch of the blades in a certain direction to give it more lift.
Servo actuators can adjust the submarine’s steering, bay doors, hatches, and rudder.
