Hi guys,
What type of couplings (motor-shaft) did you find best? I see now there's lot's of different types. For example:
Coupler GND zinc alloy flexible shaft couplings for micro motor and encoder coupling servo shaft|Shaft Couplings| | - AliExpress
GND coupling metal shaft manufacturing aluminum Clamp torque generator bellows servo motor spring quick camlock Bellows Coupling|Shaft Couplings| | - AliExpress
Two jaw D20L25 coupler D20 L25 aluminum plum flexible shaft BW coupling motor connector solid rubber pad / 6 / 6.35 / 8/10 / mm|Shaft Couplings| | - AliExpress
CNC Flexible Coupling Shaft Coupler Stepper Motor Connector D25 L30 Jaw Aluminum Alloy|Shaft Couplings| | - AliExpress
Is there any point to buy more expensive?
