Heavy Duty Electric Linear Actuator for Harsh Environments
The SLA-12K linear actuator is engineered for demanding applications that require strong thrust, stable movement, corrosion resistance and long-term reliability.
Built with a metal housing, metal gearbox, stainless steel telescopic tube and aluminum alloy outer tube, the SLA-12K provides excellent mechanical strength and corrosion resistance.
Its heavy duty design and high-power DC motor make it suitable for equipment that needs to open, close, push, pull, lift or descend under high load conditions.
Compared with hydraulic and pneumatic systems, the SLA-12K electric actuator offers cleaner operation, lower power consumption, easier wiring and maintenance-free performance. It is suitable for both industrial equipment and customized automation systems.

Built for Strength, Safety and Flexible Control
The SLA-12K combines high thrust output, rugged construction, multiple speed options and optional feedback
functions for different equipment requirements.
High Thrust Capacity
Delivers up to 12000 N / 1200 kg / 2700 lbs thrust at 6 mm/s, making it suitable for heavy lifting,
pushing and pulling applications.
Rugged Metal Structure
Metal housing, metal gearbox and high-strength wear-resistant gears allow the actuator to work in very
harsh environments.
Corrosion Resistant Design
Stainless steel stroke rod and aluminum alloy outer tube provide good corrosion resistance for outdoor
and industrial applications.
Multiple Speed Options
Optional no-load speeds include 6, 8, 12, 16, 20, 25, 38 and 60 mm/s. The actual working speed decreases
gradually as the load increases.
Custom Stroke Options
Stroke length can be customized from 10 mm to 2000 mm according to your installation and motion requirements.
Auto-Locking Function
With self-locking capability, the actuator can hold the load position after stopping without continuous
power supply.
Built-In Protection
Built-in motor overload and overheat protection help improve operational safety and protect the motor
during demanding use.
Optional Feedback
Built-in potentiometer, Hall sensor and limit switch signal output are available for position control
and synchronous control systems.
Manual Override
Equipped with manual override, allowing the telescopic rod to extend or retract with hand tools when
power is unavailable.
Wide Application Range
The SLA-12K linear actuator is suitable for many types of electrical equipment requiring reliable linear movement.
Simple DC Polarity Control
The SLA-12K linear actuator can be controlled by changing the polarity of the DC power supply.
When the brown power wire is connected to the positive pole of the DC power supply and the blue power wire
is connected to the negative pole, the stroke rod extends outward. When the power polarity is reversed,
the stroke rod retracts inward.
The actuator has two built-in limit switches. When the actuator is fully retracted or fully extended,
it will stop automatically to protect the mechanism and the motor.
Wiring Direction
- Brown wire to DC positive pole: actuator extends.
- Blue wire to DC negative pole: actuator extends.
- Reverse the power polarity: actuator retracts.
- Built-in limit switches stop movement at both end positions.
SLA-12K Linear Actuator Stroke and Installation Length
The following example shows the standard 300 mm stroke version. Stroke and retraction length can be adjusted
during production according to customer requirements.

Load Selection Notes
- The above load data is based on vertical operation conditions.
- For applications such as cellar doors, actual actuator force may be 2-5 times the door weight depending on installation geometry.
- Different speeds have different maximum loads. Select the correct speed based on both speed and load requirements.
- The maximum pulling force is slightly lower than the maximum pushing force.
Service Life Recommendations
- Continuous operation under maximum load is not recommended.
- For longer working life, we recommend working at about half of the maximum load.
- For strokes greater than 500 mm, avoid operating at maximum stroke under heavy loads.
- If the required actual stroke is 600 mm, choosing a 700-800 mm actuator is recommended.

How to Select the Right SLA-12K Configuration
To choose the proper actuator, please confirm the load, speed, stroke, installation method and control requirements.
Confirm Load and Installation
Provide the equipment weight, movement direction, mounting position and installation geometry.
Actual actuator force may be higher than the equipment weight depending on the lever structure.
Choose Stroke and Speed
Select the required stroke length and movement speed. Higher speed versions have lower maximum thrust,
so speed and load should be selected together.
Select Voltage and Control
Confirm 12V or 24V power supply, feedback requirement, cable length, connector type and whether
synchronous operation is needed.
