Flexible Coupler D19L25(6.35*8MM HOLE)

The Flexible Coupler D19L25(6.35*8MM HOLE) is a flexible shaft coupling with a 19 mm outer diameter and a 25 mm length that joins a 6.35 mm (1/4 inch) shaft to an 8 mm shaft. The 6.35 mm bore fits motors with imperial 1/4 inch shafts, including many NEMA 23 stepper motors, so this coupler links them to metric 8 mm lead screws, rods and pulley shafts. Its flexible body absorbs small misalignment and reduces vibration.

What's in the Box

• 1 × flexible coupler D19L25, 6.35 mm and 8 mm bores

Tip: Measure your motor shaft with calipers first: 6.35 mm and 6 mm shafts look alike but are not interchangeable. Slide both shafts in until they almost meet, then tighten the screws, onto the flat of the motor shaft if it has one.
