4007-4008-4012 (8mm REX Bore to 12mm REX Bore) 4007 Series Hyper Coupler (Build System: goBILDA)

(8mm REX Bore to 12mm REX Bore) 4007 Series Hyper Coupler (Build System: goBILDA)

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.
