Worm drives are compact gearboxes with high output torque for their size. This particular gearbox is rated for 20Nm and is compatible with 30 Series 14mm output shafts. The input shaft is 9mm and you will couple to a rotating power source - typically through a jaw coupling, timing belt pulley or chain sprocket.
The following shafts will fit into the output bore on this gearbox:

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.
