Figures are the highest published for each series and are not always measured the same way. A higher figure is not automatically a better choice: mounting, duty cycle, feedback, connectors and approvals matter too. An engineer will check the fit against your application before recommending anything.
What a compact actuator is
A compact actuator is a self-contained electric linear actuator, typically with a low-voltage brushed DC motor, a gear stage and an acme or ball screw driving a rod. Most include built-in limit switches and can be powered by simply connecting 12 or 24 V DC, reversing polarity to change direction. Options often include position feedback by potentiometer, Hall sensors or encoders, and onboard control electronics. They are designed for simple, cost-effective movement rather than high-precision servo control.
When engineers choose a compact actuator
Choose a compact actuator for intermittent adjustments such as opening, lifting, tilting and positioning in mobility, medical furniture, agricultural and light industrial equipment. Installation is simple and cost is low. The trade-offs are duty cycle, speed and precision: many units are rated for intermittent duty, typically around 25% on time, and brushed motors wear. For continuous cycling or tight positioning, a servo-driven rod actuator is more appropriate.
How to specify the LINAK LA14
Send these with your enquiry and an engineer can confirm the right LA14 variant or an equivalent:
- Supply voltage (V DC) and current limit (A)
- Force push and pull (N)
- Stroke (mm) and retracted length
- Speed under load (mm/s)
- Duty cycle (% on time)
- Feedback: limit switches, potentiometer, Hall or encoder
- Sealing (IP code) and temperature range (°C)
Common mistakes to avoid
- Running a 25% duty actuator continuously and overheating the motor
- Ignoring the drop in speed under load and voltage
- Not allowing for side loads in pivot mountings
- Assuming acme units always hold position under vibration
LINAK LA14: frequently asked questions
What is the LINAK LA14?
LINAK's smallest TECHLINE actuator: 750 N, up to 45 mm/s and 19 to 130 mm stroke in an aluminium housing, rated for -40 to +85 C ambient. Published series figures include voltage 24 V, temperature -40 °C, temperature 85 °C, force 750 N. It is made by LINAK A/S; Specify Motion can help source it or propose an equivalent.
Who makes the LINAK LA14?
The LINAK LA14 is made by LINAK (LINAK A/S) and is listed here for engineers comparing options. Specify Motion is not affiliated with LINAK A/S; brand names are used only to identify the product.
What is the voltage of the LINAK LA14?
The published series maximum voltage is 24 V. Individual models and sizes in the LA14 range vary, so check the exact variant against your duty cycle, mounting and environment, or ask our engineers to confirm the right size for you.
Is there an alternative to the LINAK LA14?
Yes. On published figures, G-Series Leadscrew Linear Actuator and GT44 Linear Actuator are the closest match from our supply network. An engineer confirms the fit against your application before recommending anything.
What does duty cycle mean for an electric actuator?
Duty cycle is the proportion of time the actuator can run without overheating, usually given as a percentage and a time window. A 25% rating means, for example, about two and a half minutes of running in every ten. Exceed it and the motor overheats. For continuous motion choose a unit rated for higher duty.
Do 12 V actuators hold their position when power is removed?
Many acme-screw compact actuators resist back-driving because of the screw and gear friction, and some add a brake. Ball screw versions are efficient and can back-drive under load. Vibration can still cause creep, so check the static holding force on the datasheet for the orientation and loads in your application.
