Worm Gearboxes

This shaft is designed to fit into a worm gearbox and act as an output shaft. You can install it by following these steps:

• Put the keys into the keyways on the shaft.
• Slide the shaft through the gearbox until it's centered inside.
• Slide washers onto both ends of the shaft.
• Put snap rings onto both ends of the shaft so that the washer is between the snap ring and the gearbox (There is a groove at the end of the shaft for the ring to rest inside).

Pulleys and Sprockets

If you're using 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 the system. Pulleys and sprockets can also be used to transmit rotation over a long distance. For more guidance on building a transmission system, visit our Rotary Motion Guide. Here is a list of our 19mm bore pulleys and sprockets:
