Pulleys and Sprockets

If you're using this gearbox in a rotary system that requires a lot of torque, you may be interested in pulleys and sprockets. By using a two pulleys or sprockets of different sizes, you can increase the gear ratio of system. Pulleys and sprockets can also be used to transmit the motor's rotation over a long distance.
