Factory Supply 45# Steel Single Disc Flexible Motor Couplings

 1.The main part is made of #45 steel ,the surface is bluing.

 2.The disc is made of 304 stainless steel.

 3.The disc is multilateral arc shape with eight screws,in order to improve the precision and torque.

 4.This structure iis good for anti-vibration,shaft and a longer service life.

 5.No clearance ,clockkwise and counterclockwise rotation characteristics are exactly the same.

 6.The disc structure has strong ability to compensate radial,angular and axial deviations.

 7.High rigidity ,high sensitivity.

 8.This structure will transmit larger torque and lower transmission inertia.

 9.This series coupling is commonly used in servo motor and stepper motor.
