Selection of a linear actuator
Selection of a linear actuator
(OP)
Howdy,
I am searching for a continous duty electric linear actuator. My application is for a test stand for a bicycle wheel. The actuator needs to be able to tilt the test stand from -5 degrees, to 0 degrees, to +5 degrees and back, repeatedly about a pivot point located 2 feet from the actuator. The actuator will be located under the assembly, pushing up on the load (about 600 pounds).
I am having difficulty locating an actuator that has a high enough duty cycle rating (preferably continuous duty) but is also inexpensive.
I've already looked at products by Powerjacks, Ultramotion's Bug, and Nook Industries.
Does anyone have any experience with these brands or suggestions of other brands?
Any tips or hints would be greatly appreciated!

Have you considered pneumatic? Cheap , fast, simple good for contiuous operation. Look at Festo, SMC, Bimba, Fabco. Parker

I have worked extensively with linear actuators in the past few years, to the point where vendors were learning from me about their own products. Don't count on finding a continuous-duty electric linear actuator of that size anywhere. Maybe 15% duty if the load is light enough.
For continuous duty linear, I recommend pneumatic actuators.

Avoid linear actuators unless there is no other choice.
You don't need position control to accomplish the functional requirement listed in your first post.

These guys made linear actuators for boiler burner tilts which were continuously modulating service.

These guys too: htt
I think among these you should find something - BUT - cheap isn't an option, so if you insist on cheap, save your time.
To tick - were you engaged with these either of these guys at all in your quest for linear actuators?

Rotork is more industrial. I do know who they are (even met a few of the folks here in Milwaukee). Different league, very different $$$.
The motion described in the OP is a bit more rigorous than what one would consider to be continuous modulation.
Pneumatic isn't accurate enough? How accurate do you need to be? Can the accuracy be controlled by other means? OP doesn't mention speed at all, so he doesn't know how much power he needs.

Hi NathanielM,
I think for your application power screw with reversible direction motor will be sufficient and reasonable price.
