Could this be mounted outdoors in ny ? e.g. temperature range ? to pull a church bell rope, in a small bell tower

I think it would depend on the weight of the bell and the length of pull needed to make the bell ring. I used it for a rope with a skeleton attached to it ( prob 5 lbs at most) but to get a good swing had to add an extension arm. As for outside, I live an AZ but did house mine from the elements in a small box. I think it would be wise to do so. If it is not working continually it should need a little lubrication once a year. Hope this helps.

How do you adjust the speed? (Voltage?)

Hello, you can use the controller to reduce speed, thanks!

When stopped, will the arm lock or will it drift?

No. There is a gearbox that provides a lot of torque to the drive arm and it is almost impossible to move it by hand. There is a very slight bit of momentum when removing power but then it's pretty much locked.

In the video, it shows two other component. Do you have links to them (power supply and speed control)?

Hello, pls click https://www.amazon.com/dp/B0721XMCPB and https://www.amazon.com/dp/B01G6GO12Y to confirm the power supply and controller, thanks!

Mecánicamente versátil

Es un actuador lineal, bastante versátil, cumple con mis necesidades y exigencias, por el diseño que tiene no se necesita de mayor tamaño, la fuerza que pone el fabricante en la tabla por las diferentes RPM al parecer las cumple
