Where to get Linear Actuators, Ballscrews, Lead Screws.

After getting my project together I find that the force needed to lift and lower the arm is 15# to 20#. So my plan of using a heavy duty servo won't work. I've started to look in to linear actuators, ball screws or lead screws but can't find any that will work. Besides the heavy lifting capacity I'm looking for 6 volt DC operating with a throw around 1-3/4 inches. The 6VDC is what the radio BEC provides.

Yeah, I've checked Servo City. Nothing there would fit my application.

Linear Actuators we use are by Firgelli Auto (www.Firgelliauto.com)

We have used many linear actuators before and we found that Firgelli automations Inc has the best quality, best pricing and larges online range of all. They even ship out next day. They claim to have 100,000 actuators in stock at any time. WE also purchased their TV lifts which work very well too. Link also below

Hi Guys,
Please be aware Firgelli Technologies and Firgelli Automations are NOT the same company.
Firgelli Technologies (where I work) makes the receiver ready micro linear servos with strokes of less than 5.5 inches and forces to 40 lbs.
Firgelli Automations makes much larger actuators for TV lifts and are owned by different people in a different city.

Who sells Firgelli actuators at a discount?

I see that the Firgelli Technologies L16 option R linear actuator is for RC applications. Other than ordering directly from Firgilli at $70 each is there any place that sells them at a discount?

It is a good practice to counterbalance arms with either weight or springs / gas shocks so the motor does not have to work very hard to hold the arm up. Doing this would allow you to use a servo again and may result in faster actuation and a lower overall cost. You could also check out the heavy duty servo kits at servocity which take a normal servo and gear it down.

Many electric car seats have great linear actuators built into them. I have used several with a HK brushed motor controller. I have found some at Surplus Center if you want something new, but junkyards, and Ebay will probably turn up more options than you care to sort through. Even undervolted they will provide way more torque than you would need. The hardest part is finding one with the right dimensions.

I've got some linears for sale. Take a look on my website:
http://robot-one.com/for-sale.html

Bout six items down.

Would they work? You would need to add motor and control.
