Miki Pulley Bellowflex (Resin Bellows Coupling)

The Miki Pulley Bellowflex coupling uses a highly elastic resin boot made from polyester resin, which absorbs vibration and cuts down on shaft reaction forces caused by misalignment during installation. It stays compact and lightweight thanks to this design, and since it’s built as one piece, installing or removing it is straightforward.

There’s no backlash to worry about, which makes it a good fit for precision positioning and measurement tasks that use stepper motors or encoders. It’s available in three sizes, all flexible, with operating torque ranging from 0.4 to 1.5 N·m. This high damping rubber coupling also helps reduce the risk of resonance when used with servo and stepper motors.
