Perfect for servo motor
Fitment was precise on my 20mm shaft. The elastic design helps absorb minor misalignments effectively.

Smooth operation
Vibration is gone after swapping out the old coupling. Great for precision work on servo motors.

Good value
Works well but instructions could be clearer on torque settings for the setscrews. Otherwise a solid product.
