Frequently asked questions
How do I connect the two bores?
Fit one bore to the motor shaft and the other to the driven shaft or lead screw. The two bores are 10 mm and 6.35 mm, so match each end to the correct shaft diameter.
Can this coupler handle misaligned shafts?
The flexible design tolerates small angular, parallel and axial misalignment. It is not intended for rigid, high-torque connections where shafts must be precisely aligned.
