The OD is 1 and 3/8 inch...The ID you can get in 5/8 in. or 3/4 in. On Amazon they are like 10pcs. for $15 or 4 pcs. for $8....The Harbor Freight wheels have a 5/8 ID for like on a 5/8 bolt or a 5/8 shaft...The new bearings fit tight on a rod/bar but go on a bolt/stud better I think because a bolt is made to fit inside a 5/8 hole and a 5/8 bar is made to be 5/8...When I use a bar/rod for an axle I use a locking collar they are cheap and reuseable...When you have a bolt for the end of the axle you should use a new lock nut every time you take off the wheel, like they don't hold as good after the first time...
Nice I can finally use those on cheap go karts. What’s the size of the new bearings? I.D and O.D?
