This 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.
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 supports bearings.
It has high torsional stiffness.
Applicable range: T8 screw rod, thread pitch 2mm, lead 8mm
The T8 screw rod position is increased to save space.
