Brass Oldham Coupling T8 Z-Axis Lead Screw Shaft Coupler 16mm Oldham couplings are three-piece flexible shaft couplings that are used to connect driving and driven shafts in mechanical power transmission assemblies. This Oldham coupling is made of brass, which reduces friction and has sufficient strength. CNC machining controls the clearance at the connection location. 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.
