according to me the pneumatic solution generates vibrations at the ends of the race that destroy the coating...
electrical actuators are softer.

bha... objection to your honor.
as for all things, depends on the components you choose.
you can take progressive start valves to start the cylinder gently. you can use a plc to control the position and adjust a proportional valve. you can think of using the end brakes of the cylinder properly calibrated. Clearly it must be "brand" stuff... if not you really risk having vibrations.
but the same risk you have with electrical actuators controlled by inverter id bad quality etc etc etc etc.

I remembered that years ago I had made winders with a mechanical translation device produced by andantex are devices with automatic reversal and adjustable feed step that are called uhing, in attachment you will find the catalog page

Open up! they gave me the authorization to buy something already done to adapt ad hoc :smile:

I looked at this catalogue and they'd be perfect. The company that sells them is close... everything perfect... but... how much they cost? ?
I sent the request for quote but still nothing...you don't remember the price more or less?

Thank you so much!

I used them about 12 years ago were of an average size and cost about 900.000 lire I think that for your application are well those of the smallest size if you buy the complete sled you just have to connect a scooter, I don't think they cost a madness at the bottom they work varying the inclination of a bearing in the rotating tree.
the company is a multinational if you go to their website http://www.andantex.it find all the info regarding when I took them I also have a branch in Italy near Milan.
