3/8 Shaft Coupling

Coupling, Flexible-beam, 1 1/4 ( 1.250) dia x 1.5 long w/ 3/8 bore in each end.  Black Anodized aluminum.

 

Fits NEMA 34 motor shafts. 

 

Rated torque is 255 oz-in, Peak torque is 510 oz-in Max RPM is 5000 

 

This is a clamp style coupler and does not require a flatted shaft.  The clamp style fit is more

effective than a set screw as it will not marr the motor shaft.  Works on round or D-flatted shafts.

 

The flexible beam corrects for a slight misalignment between the mating shafts, reducing wear and

tear on bearings.  Also may help to dampen stepper motor resonance.
