I wanted to use it downwards, I selected it from the whole diameter and screw diameter. It is quite smooth without lubrication. I turn several things at the same time, but it is not too noisy. Of course, it can not be silence. As we secured the amount quickly, we delivered it serially, but it was saved because the response was still early. I am fortunate if it is a bit cheaper, but downward use will not come out so much so it might be this one.
