The Oldham coupling is made of brass, reduce friction and has sufficient strength, high precision to make the connection gap between three parts lowest, low movement of inertial
high torsional stiffness, Protect driven parts and support bearings, used to advoid the effects for large radial misalignment
The use of this shaft coupling for the Z-axis screw of the 3D printer will reduce the printing quality problems caused by the swing of the hot bed during the printing process.
The center distance between two holes is 18mm, fixing hole is M3, Used with 8mm lead screw
Compatible with Creality CR10 CR-10S Pro Ender-3 ENDER 3S Ender 3 Pro, Ender 3 V2 3D Printer and other 3D printer
