This shaft is made of 1045 carbon steel, precision ground to exactly 17mm, 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.
17mm is one of the 'core' shaft diameters in our mechanical product line - in addition to 8mm, 12mm and 25mm. 17mm is a great diameter for higher power belt transmissions (GT5), #40 chain systems.
We also sell the 17mm shaft with a full length keyway.
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 17mm 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:
