Flexible plum motor coupling XB D20L30 6.35 mm / 8 mm

Sturdy but still flexible motor coupling for 6.35 mm motor shaft, great for driving high-precision axes with lead screw or threaded rod

This 8 mm XB type motor coupling is a great solution for driving axes which require high-precision low-backlash movement. The red elastomer provides a semi-flexible solution, allowing the axis some flexibility in the perpendicular  displacement, but none in the length. This reduces friction in the axis, while maintaining the precision. This motor coupling is for usage in your 3D printer's Z-axis as well as CNC machine axes. The coupling fits on all our 6.35 mm shaft stepper motors and can be used in combination with the 8mm threaded rod or tr8x2 / tr8x8 lead screws.
