Flexible Coupler D19L25(4*6MM HOLE)

The Flexible Coupler D19L25(4*6MM HOLE) is a flexible shaft coupling with a 19 mm outer diameter and a 25 mm length that joins a 4 mm shaft to a 6 mm shaft. It lets a small motor with a 4 mm output shaft drive a 6 mm lead screw, rod, encoder or pulley shaft, while its flexible body absorbs small misalignment between the shafts and reduces vibration that would otherwise wear the motor bearings.

What's in the Box

• 1 × flexible coupler D19L25, 4 mm and 6 mm bores

Tip: Slide both shafts in until they almost touch in the middle, then tighten the screws firmly, onto the flat of the shaft if it has one. Keep the two shafts in line; the coupler is designed to absorb small misalignment, not large offsets.
