Weight & Inertia figures are at maximum bore and minimum adaptar diameter. Maximum speed corresponds to smallest standard adaptar . Standard construction has hubs in close grain cast iron for all sizes.Centre spacer are cast iron upto size 600 and cast steel for larger sizes.Flywheel adaptars are of steel. Disc packs are of stainless steel for all sizes. Alternative materials including forged steel for hubs with larger bore capacity available on request.
