The idea is great and it works but the problem is. Whoever engineered the part where it rotates around didn’t get some spect right. The round rotating collar where the 2 bearings sit at rub on the top round plate that is fixed on the equipment and the bottom round plate that is bolted on in place by the socket head bolt. There are a spring washer and 2 flat washer that don’t work if you put it the way you’re instructed to. I had to put on the rotating arm first then 2 flat washers plus the spring washer then the round bottom plated and bolted that way to make it work. So I wouldn’t put to much stress on the inner race of the hearing
