China Linear Actuator for Old Man Chair

Q: What if I need an actuator using a Stroke length or Force that you don't stock?
A: We have many other actuator configurations available, and we'd be happy to make a Custom Order for you. Please visit our Custom Orders section or contact us with your requirements.

Q: How can I mount your linear actuators?
A: Every linear actuator we sell features mounting holes on each end of the actuator body. Combine these with our mounting brackets (with a 180° turning radius) and you have a full range of mounting solutions. Remember to mount the actuator on something that can bear its weight too.

Q: Do your actuators come with internal limit switches? How do they work?
A: All JDR actuators come equipped with builtin limit switches. The limit switch stops the actuator once it has hit the end of its complete travel length in either direction, until polarity is reversed. This prevents damage from over-extension and also conserves electricity for low power consumption applications.

Q: What are the actuator dimensions and/or specifications?
A: The technical data section of our website contains measurement details, product specifications, and wiring schematics. This includes actual CAD model drawings of each product. Each individual product page also has a link to its own specifications, And if you require additional information please contact us!

Q: Can the actuator hold a load when partially or fully extended?
A: All JDR actuators can hold their rated Force weight when stopped at any point along its stroke length. If your actuator is rated for 400 lbs, it will hold that amount when stopped, even if the power is disconnected.
