1.The main body is made of 45# steel and connected by expansion sleeve.

 2.The main body adopts blackening treatment ,which has simple structure and is convenient for inspection and maintenance.

 3.Diaphragm adopts 304 stainless steel.

 4.Convenient installation,compact structure,suitable for high speed operation.

 5.High colletiion capacity and low moment of inertia.

 6.Adopt 8screw diaphragms with multiateral arc,with high precision and large torque.

 7.Zero rotation clearance : clockwise and counterclockwise rotation characteristics are exactly the same.

 8.Vibration can be absorbed,and the middle diaphragm compensates for angular and axial deviation.

 9.Large torque transmission is acceptable ,which is safer and more reliable and has high performance .

 10.It is commonly used for high speed connection of servo motor,stepping motor and screw rod.
