This is a fairly simple belt tensioner for the Y axis. To install, just attach the screw into the bearing holder with the nut using washers on both sides, then move your existing bearing setup into the new carrier. Use the wingnut and a washer to pull the bearing holder towards the back of the 2020 mount.
