Helical Flexible Coupling (coupler).
General purpose with light to medium duty.
This is economical and maintenance free coupling for variety of applications.
It is 7/8 dia x 1" lg w/ 1/4 bore in each end.
Black Anodized aluminum.
Attachment via two set screws for each side. Fits most NEMA 23 motor 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.
Strongly recommended for attaching an encoder shaft to a motor.
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.
Clamp screw takes a 3/32 Hex (Allen) wrench.
