The sprockets are made on precision controlled equipment in a modern 25,000 square foot facility. The teeth are machined to the latest standards, this ensures the maximum chain life and more efficient power transmission. Machining is carried out on a gear hobbing machine. The teeth and the outside diameter are cut at the same time. This makes sure that the teeth are concentric to the sprocket centre. Most OEM’s demand a maximum run-out of 0.5mm, all AFAM sprockets have a maximum run-out of 0.2mm - more than twice as accurate as the industry standard!
