The equalizing element of an EK coupling is the elastomer insert. It transmits the torque without backlash and vibration.

The elastomer insert defines the features of the entire coupling and/or of the entire drive system.

The coupling is backlash free due to pretensioning of the elastomer insert between the two coupling halves.

The Servomax-Coupling compensates for lateral, angular and axial misalignment.

Due to the electrically conductive properties of insert D electrostatically charge of the coupling is prevented. This eliminates sparks during normal operation (Explosive areas). Technical data available.
