25mm single ended shaft for series 50 worm gearboxes. W/ keyway and keys included as well as a pair of washers and snap rings for retention in the gearbox.

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 Primer. Here is a list of our 25mm bore pulleys and sprockets:

Rotary Bearings

Systems with heavy loads or pulley/sprocket assemblies often put a lot of sideways strain on the shaft. In such a system, you can use rotary bearings to protect and support the shaft:
