Replacement roller for kitchen cabinet

We have a 5/8" nylon ball bearing wheel, our 10-142, that might fit. Your roller might have worn down from use. You would drill out the rivet and screw on the new wheel with something like our 33-087 screw. You might also want to add a drop of Lock Tite on the screw threads to secure the wheel. You can get the Lock Tite at your nearest hardware store.
