Linear Actuator Guide
What is a linear actuator?
A linear actuator is a device that creates motion in a straight line. Instead of rotating like a motor shaft, it extends and retracts a rod to move a load forward or backward.
An electric linear actuator normally combines a DC motor, gearbox, screw mechanism, limit switches, housing, and extension rod. It is widely used when equipment needs controlled lifting, pushing, pulling, tilting, opening, closing, or positioning.
Simple electric control
Most 12V or 24V linear actuators can extend and retract by reversing polarity through a switch, relay, controller, or automation system.
Clean alternative to hydraulics
Electric actuators can reduce oil leakage, compressor noise, hoses, and maintenance in many light-duty and medium-duty motion systems.
Repeatable positioning
Optional Hall sensor or potentiometer feedback supports position monitoring, synchronized motion, and controlled automation.
Custom mechanical fit
Stroke length, installation length, mounting bracket, connector, cable length, speed, force, and protection rating can be adjusted for your project.
Linear Actuator Applications
Where are electric linear actuators used?
Linear actuators are used anywhere a machine needs controlled straight-line movement. Different models can be selected for load, stroke, speed, protection rating, control method, and installation space.

Solar Tracking Systems
Solar panel angle adjustment, photovoltaic tracking structures, outdoor energy equipment, and weather-resistant positioning systems.
Automotive & Mobile Equipment
Tailgates, access hatches, engine covers, RV systems, marine covers, service panels, and special vehicle mechanisms.
Robotics
Linear positioning axes, robot arms, inspection robots, compact motion modules, and controlled push-pull movement.
Smart Furniture
Recliners, lifting desks, adjustable beds, massage chairs, TV lifts, hidden cabinets, and ergonomic home automation.
Outdoor Machinery
Snowblower chutes, ventilation doors, protective covers, waterproof access panels, and harsh-environment outdoor systems.
How to Choose
How to choose the right linear actuator?
Choosing the right electric linear actuator depends on the actual load, stroke, speed, duty cycle, installation space, working environment, control method, and expected lifetime.
Before requesting a quote, please confirm:
- Required load force: N, kg, or lbs
- Stroke length: how far the rod needs to extend
- Voltage: 12V DC, 24V DC, 36V DC, or 48V DC
- Speed requirement under load
- Working environment: indoor, outdoor, wet, dusty, high temperature, or low temperature
- Control requirement: simple switch, relay, controller, Hall sensor, or potentiometer feedback
- Mounting space: retracted length, extended length, and bracket type
| Selection Factor | Why It Matters |
|---|---|
| Load Capacity | The actuator must handle the real push or pull force with safety margin. |
| Stroke Length | Stroke defines the travel distance of the actuator rod. |
| Voltage | Common options include 12V, 24V, 36V, and 48V DC depending on your power system. |
| Speed | Higher load usually means lower speed. Speed should be checked under real load. |
| Duty Cycle | Heavy-load actuators often need rest time between operations to protect the motor. |
| IP Rating | IP66 or IP68 models are recommended for wet, dusty, or outdoor environments. |
| Feedback Signal | Hall sensor or potentiometer feedback helps with position monitoring and synchronization. |
| Mounting Design | Bracket, pin size, retracted length, and installation length must fit your machine. |
| Customization | OEM options can include cable, connector, housing, stroke, voltage, speed, and control interface. |

FAQ
Frequently asked questions about electric linear actuators
These answers help customers quickly understand actuator selection, applications, waterproof ratings, and customization.
What is the difference between a 12V and 24V linear actuator?
A 12V linear actuator is common for vehicles, battery systems, RVs, boats, and small equipment. A 24V linear actuator is often used in industrial automation, medical equipment, agricultural machinery, and systems that need more stable power distribution.
What does IP66 or IP68 mean for a linear actuator?
IP ratings describe protection against dust and water. IP66 is suitable for strong water jets and dusty environments. IP68 models are designed for higher waterproof protection, depending on the actuator structure and test condition.
Can a linear actuator stop at any position?
A basic actuator normally stops at the built-in limit switch positions. If you need intermediate position control, choose a model with Hall sensor, potentiometer, encoder feedback, or use an external controller.
What information is needed for a custom linear actuator quote?
Please provide load force, stroke length, voltage, speed, working environment, duty cycle, installation size, mounting method, feedback requirement, quantity, and any drawings or application photos.
Are electric linear actuators suitable for replacing hydraulic or pneumatic cylinders?
In many applications, yes. Electric linear actuators can reduce hydraulic oil leakage, air compressor requirements, hoses, and maintenance. However, very high force, very high speed, or continuous-duty applications should be checked carefully before replacement.
