I got frustrated adjusting the torch height after short periods of cutting. This setup aligns the bearing with the torch centerline so will work with the table extension without losing any travel. Parts are less than 10.00. Picked up metal roller bearing at harbor freight for 2.00. unit slides into 2" sq tube and attaches with the bearing block screws. Fought with the screws and would through drill the tubing for allen wrench access. Locks in tight. Used for 2 hrs and no sagging gantry. Requires some welding.
