great little servo, get what you pay for

Review by Hannah

This little servo is so easy to implement and works pretty well. The pager motor that runs it can sometimes get dislodged from the gear system which makes it stop working, but you can open up the box and push it back into place (and add a bit of glue/epoxy to get it to stay in place).

limited use

Review by gary

I am into model railroading and this linear servo is perfect for switching track turnouts, that need minimal torque to operate!

Fully satisfied

Review by Yves

I like the size of the linear servo, it can be installed in a thin space. The travel of the servo can be adjusted very easely.

Small but not perfect.

Review by Chris

As far as I'm aware you won't find a linear servo of this size anywhere else.Works fine by itself,but I needed four of them to be perfectly synchronized,and out of the first four three were but one wasn't.So I had to buy another one to get a set of four that would keep up with each other.

Good price / quality

Review by Luben

Probably the smallest linear servo you can get on the market. Opens horizons for new miniature applications. The torque is not great - should not exceed 140-160 g load. All gears inside are plastic so consider not to use it in heavy duty applications. Because of the backlash of the central nut and the printed resistive tracks of the potentiometer (directly on control PCB) it can't be used for very precise positioning but is excellent for discrete states (like open or close a vent, etc.).

The pure move is not 20mm as stated but 17mm, it takes 1s to move from one end to the other on 3.6V. Because of the plastic gears and the coreless motor the noise when moving is low.

I would recommend you get some samples to play with, for sure you'll get new ideas where to use it.

This servo easily receives 5 stars. It is small powerful
and built strong. Great product!!
