12mm Aluminum REX™ Shafting

Aluminum REX™ Shafting is the lightweight alternative to the Stainless Steel REX™ Shafting.  It provides many of the same advantages, creating a positive drive while being able to rotate in a 12mm diameter bearing without unnecessary rotating mass.  The ends of the Aluminum REX™ Shafting have M4 threads for use as a structural element too!
