Frequently asked questions
Is the 6.35 mm bore suitable for 1/4 inch shafts?
Yes. 6.35 mm is equal to 1/4 inch, so that end fits a 1/4 inch shaft. The other end at 8 mm fits an 8 mm shaft. Measure your shafts before installation.
Why choose a flexible coupling for a stepper motor and lead screw?
It compensates for small misalignment between the motor shaft and the screw, reducing side loads on the motor bearings and the lead screw, which helps keep motion smooth.
