Elastic element – three-layer rubber HNBR
The STEPFLEX elastic element consists of three layers of rubber of varying hardness.
The centre, widest part is made of hard rubber, with a soft rubber layer on either side.
This rubber element design provides a backlash-free effect. These couplings dampen vibration faster than flexible couplings that use metal in their elastic components. This suppresses the resonance phenomenon that can occur with stepper motors, avoiding resonance over a wide range of operating speeds. It also provides stable, high-speed control.
