I previously had this one https://a.co/d/04U2134B, but it would develop play and start to bind noticeably in just a few days. I sprayed oil into the bearing, but it was just a temporary solution. It also turned cable black (this was before I oiled the bearing) and wore the cable to the point where I had to replace it after just a few months. This is my favorite pulley: https://a.co/d/04U2134B It has a sealed bearing and has not worn out over several months of daily use (20 clients per day, days per week). Very smooth and has not developed any play in the bearing.
