Miki Pulley Stepflex
Technical overview of Miki Pulley Stepflex for engineering discovery and identification.
Stepflex STF couplings
Miki Pulley Stepflex STF couplings use laminated rubber elements (HNBR) for stepper motor applications. Manufacturer evidence describes high damping and low reaction force characteristics suited to stepper drive resonance control.
Stepper drive considerations
Stepper systems exhibit oscillation at certain speeds. Coupling stiffness and damping influence settling time and positional accuracy. Match Stepflex selection to motor frame, bore and expected acceleration.
Compared to Servoflex
Servoflex emphasises low inertia for servo motors; Stepflex STF addresses stepper-specific damping needs. Review the Miki Pulley couplings hub for the full series comparison.

Common questions
Servoflex is typically preferred for servo duty. Stepflex STF is tuned for stepper applications. Send duty data if you are evaluating either series.
Mounting styles vary by series in the Miki Pulley catalogue (clamp, set screw, etc.). Confirm against published dimensions for your shaft.
