This shaft is made of 1045 carbon steel and is 12mm in diameter. This is the same diameter as the gearbox output shaft on all our NEMA 23 steppers as well as larger DC motors. This shaft has a keyway machined in the full length of the shaft for higher torque applications.
If you need to connect this shaft to a motor or another device with a shaft, you can use a shaft coupler:

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 12mm bore pulleys and sprockets:

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:
