12mm Precision Ground Rotary Shaft (no keyway)

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.
