Just tried a 50x4mm belt on 4602-054 and far too loose. However, 4602-320 is a 40x4mm belt and is a nice tight fit so should work well as a wheel.

Without going into the warehouse to try it, not sure for certain. Two issues are whether the belt would protrude enough over the edge of the pulley and whether it would be a tight fit. A 4mm diameter belt would be better and I note that we do not have any listed but we do stock them so I shall investigate why they are not on the website. That leaves the inside diameter, that would require a physical check which I shall try and do and report back.
