2-Pack Oldham Coupling Couplers Compatible with VzBot, BLV and Other 3D Printer Z axis T8 Lead Screw Hotbed (Oldham Coupling)

• The Oldham coupling is made of brass, reduce friction and has sufficient strength, produced by CNC machine, high precision to make the connection gap between three parts lowest, low movement of inertial
• Its function is to improve the printing quality from the problems caused by the swing of the heat bed during printing, like subtracting the effects for the clearance of not straight lead screw when printing
• If the lead screw is not straight, the printing precision will be a problem, then this kit will solve it
• high torsional stiffness, Protect driven parts and support bearings, used to advoid the effects for large radial misalignment
• OD is 22mm, The center distance between two holes is 16mm, please must measure your lead screw nut installation holes distance before purchasing.
• This kit is compatible with VzBot 3D Printer, BLV 3D printer and other 3D printers with T8 lead screw Z axis which is using 16mm center distance installation hole lead screw nut.
• Package: 2pieces couplings
