T8 oldham coupling v2

The design is provided by the VzBoT team.This T8 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. High-precision CNC machining screw thread, tighter fit and more stable. It is recommended to buy high-quality screw rods, which will achieve the best results. Note: The kinematic feature of this part increases the error tolerance space, so a small amount of clearance can be used normally. It is small in size and easy to install and disassemble Compact size, low moment of inertia Adapt to large radial misalignment It protects driven parts and support bearings It has high torsional stiffness Good surface finish and longer service life   Applicable range: T8 screw rod, thread pitch 2mm, lead 8mm   The T8 screw rod position is increased to save space  Comes with 2 per item 1Compatible VzBot 3D Printer Blv 3D Printer 3D Printer Using T8 Screw For Z Axis
