Listing is for quantity 1 pc. Order additional quantity if more than one is desired.
5mm x 1/2" Coupling, Flexible-beam clamp style, 1" dia x 1 1/8" lg w/ 5mm bore in
one end and 1/2 bore in other end. Blue Anodized aluminum.
Fits NEMA 17 motor shafts. Also 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 mar 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.
The result is a zero backlash connection. This coupling requires no end machining with 1/2 lead screw.
Max torque = 340 oz-in If a size other than 5MM ID is needed, the buyer can enlarge the 1/4 end up
to 1/2 inch. Only the size listed is available for this Ebay item.
Flat Rate shipping via USPS priority mail. No additional shipping charge for multiple quantity order.
