5 x 8Mm Plum Blossom Coupling Flexible Spider Shaft, Coupling CNC Stepper Motor Coupler Connector D20 L25

Flexible couplings adopt imported polyurethane as elastomer material and sleeve material is high strength aluminum alloy which has good character of oil resistant, electrical insulation.
Plum blossom coupling length is 25mm / 0.98in and the outer diameter: 20 mm / 0.79in that has compact size and smooth surface.
The nominal torque is 10 (N.m),allowable speed is 10 (r/m) and the allowable torque is 8 (N.M),the structure is simple, easy to install, buffer, damping, convenient to disconnect.
Clockwise and counterclockwise rotation properties are identical and the elastic connection, it can absorb vibration, compensate radial, angular and axial misalignment.
Shaft coupling is often used to connect servo motor stepper motor, encoder, screw driving, machine platform etc.It is widely used in the shafting transmission of various mechanical devices, such as pumps, fans, compressors, petroleum machinery, printing machinery.
