Single duty sprockets are manufactured to where every tooth gets engaged evenly on each revolution.This is because double pitch sprockets are manufactured with a special tooth profile that allows for the roller to properly seat and engage with the teeth of the sprocket.
Our in-stock standard double pitch sprockets are manufactured out of SAE-1045 case hardened steel with extra-hardened teeth and coated with black oxide. These sprockets are extremely durable, high-strength, and manufactured to high precision tolerances.
Stock double pitch sprockets include standard roller and carrier roller style, single duty sprockets are made to order and typically take anywhere from a few business days to a few weeks to manufacture based upon our factory loads and sprocket specifics.
