4007 Series Hyper Coupler (8mm REX™ Bore to 12mm REX™ Bore)

This 8mm REX™ to 12mm REX™ coupler is a compact, balanced way to fasten an 8mm REX™ shaft to a 12mm REX™ shaft.  The 21mm overall length allows you to slide the coupler down inside of 1120 Series Channel even when one of the two shafts is inserted half-way through the inside cavity.  The bores of the coupler are profile-matched to create a positive drive.  That, in combination with four pinch bolts, provides an extremely solid connection that is able to hold loads in both the radial and axial directions with ease.
