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.
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.
V-belt pulleys or sheaves mate with drive belts in numerous power transmission applications. They are made in many configurations such as tension idlers and variable speed / ratio pulleys.
Worm gears are cylindrical gears with a spiral thread that drive mating worm wheels in high-reduction gearset applications. They operate on non-intersecting perpendicular axes.
