SSPTP Sprockets are teeth like projections arranged on a wheel rim to engage the links of a chain. They engage chains in many different power transmission and conveyor systems. Sprockets are mainly made of cast iron, sintered metal, and carbon steel. These are reliable drive system for long running, continuous drive applications with maximum absorption of shock and minimum torque load. Sprockets are connected with each other by the help of chain in which on one end of chain is a small sprocket located on engine, which rotates due to the force of engine. These sprockets must be checked thoroughly once in a month for ensuring its high performance and if teeth are worn down or are broken they should be replaced.
