English roller chain sprockets engage chains in many different power transmission and conveyor systems. Sprockets and chains are often an economic, reliable drive system for long running, continuous drive applications with limited shock and torque loads. English sprockets are classified according to ANSI number designations.
Belt drives are attached between a sprocket at the transmission output and a sprocket attached to the rear wheel. They require no lubrication, so they are one of the cleanest final drive systems.
English pitch timing pulleys mesh with same-pitch timing belts on synchronous drives where maintenance of speed ratio is important. These pulleys have an inch-based pitch designation.
Metric roller chain sprockets engage chains in many different power transmission and conveyor systems. Sprockets and chains are often an economic, reliable drive system for long running, continuous drive applications with limited shock and torque loads. Metric sprockets are classified according to ISO number designations.
Metric pitch timing pulleys mesh with same-pitch timing belts on synchronous drives where maintenance of speed ratio is important. These pulleys have a millimeter-based pitch designation.
