Your pictures shows a plastic connector between the motor and collet, how well do you think it handle the reciprocal motion?

It seems to be functioning quite well and I have put several hours on mine

What is the stroke length? How many strokes per minute minimum and maximum?

This is ultrasonic and not profiler

Is there any warranty?

I'm not sure if there is a warranty but considering the price is not even one quarter of the price on most ultrasonics l considerate a good investment are you smiling regularly with no issues

What kind of air coupler is used in this item?

That is an excellent question. The air coupler is not recognizable to me and doesn't fit any connections that I know of (industrial, automotive or ARO), and there is no way to switch it out, so probably going to have to return the item.
