E3D Flexible Motor Coupling

These are flexible shaft couplings that are particularly useful for connecting motors with threaded rods or threaded spindles on the Z-axis. These help to reduce or eliminate the dreaded Z wobble that plagues many machines.

Each has four M3 setscrews - 2 for each shaft, for the best concentricity and grip. These 5 mm couplings are ideal for connecting motor shafts with M5 threaded rods or with certain threaded spindles that have a part turned down by 5 mm. The dimensions of this product can be found in the technical drawing in the picture gallery above.
