Vite trapezoidale TR8X2 (8 mm / 2 mm per rev. / 30 cm)

This 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 5 mm shaft stepper motors and can be used in combination with the 8mm threaded rod or tr8x2 / tr8x8 lead screws.

This 5 mm / 8 mm flexible motor coupling is a great solution for driving axes which require high-precision movement. The coupling allows for flexibility in all three axes, reducing the wobble on the rod. This removes a lot of the unwanted motion of the rod. 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 5 mm shaft stepper motors and can be used in combination with the 8 mm threaded rod.
