Typical applications
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 GT44 Linear Actuator
Send these with your enquiry and an engineer can confirm the right GT44 Linear Actuator variant:
- 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
GT44 Linear Actuator: frequently asked questions
Can you help replace GT44 Linear Actuator or source the original?
Send the full model code, quantity and required date. Our engineers can check original-part availability and assess suitable alternatives, including supply-network options where appropriate. We confirm compatibility and any changes needed before recommending a replacement.
What is the GT44 Linear Actuator?
Worm-gear acme screw DC actuator rated 6,000 N push with aluminium housing and stainless rod, for lifting beds, wheelchairs and automation. Published series figures include force 6,000 N, stroke 400 mm, linear speed 6 mm/s. It is available through our supply network, and our engineers can confirm the right variant for your application.
What model codes are in the GT44 Linear Actuator range?
The GT44 Linear Actuator range includes GT44-1235, GT44-2435. The table on this page lists each published model code with its key figures. Send us the code you use, or the one you need to replace, and our engineers will confirm availability, lead time or the closest equivalent.
Who makes the GT44 Linear Actuator?
The GT44 Linear Actuator is part of a range available through our supply network. Send us your requirement for pricing, lead time, datasheets and CAD.
What is the force of the GT44 Linear Actuator?
The published series maximum force is 6,000 N. Individual models and sizes in the GT44 Linear Actuator 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.
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.
