Description
Our double pitch precision roller chain sprocket is suitable for low speed, low mechanical power, and large sprocket center distance chain drive applications. It is integrally forged using medium carbon steel. Professional gear hobbing machines are adopted for the teeth creating. Our double pitch sprocket wheels are durable and wearing resistant, due to the integral quenching and tempering, as well as the high frequency quenching for the teeth.
