I would strongly encourage you to use the GT2 tooth profile rather than the english series. There has been a lot of design efforts that have gone into improving the tooth profiles to give higher load capacity in a smaller belt, and these advancements are only present in the metric profiles with GT2 being the best. For this reason, we use GT2 or HTD if we can't get GT2 in the size we want. There is a great document on the gates website that outlines the power rating differences, unfortunately it is buried down in there. It is well worth finding and doing the math on the proper sizing, or you run the risk of stripping the teeth off of your belts.

Since McMaster only carries the english profiles, you need to get them from someplace like SDP-SI.
