DNB series aluminum alloy high rigidity single disc coupling with single step keyway and eiht screws cooupling

 1.The main part is made of high strength aluminum alloy with keyway design .

 2.The diaphragm is made of 304stainless steel.

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

 4.This structure is good for anti-vibration safty and longer fservice life.

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

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

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

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

 9.High rigidity ,high sensitivity.
