This shaft is made of 1045 carbon steel, precision ground to exactly 12mm, and chrome plated. The production process is the same as linear shaft - except the shaft is not case hardened, allowing you to easily drill and machine the shaft. 12mm is one of the 'core' shaft diameters in our mechanical product line - in addition to 8mm, 17mm and 25mm. 12mm is a great diameter for higher power belt transmissions (GT5) and #25 chain systems. We also sell the 12mm shaft with a full length keyway.

    • Shaft Couplers

    If you need to connect this shaft to a motor or another device with a shaft, you can use a shaft coupler:

    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 12mm 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:
