Function
| The equalizing element of the EK coupling is the elastomer insert. It transmits torque without backlash or vibration.The elastomer insert defines the characteristics of the entire drive system. | Backlash is eliminated by the press fit of the elastomer into the hubs. Through variation of the Shore hardness of the elastomer insert, the coupling system can be optimized for the ideal torsional characteristics. |
Sizes 2 - 800
Shore hardness 98 A Shore hardness 64 Sh D Shore hardness 80 Sh A Shore hardness 65 Sh D Shore hardness 64 Sh D
Sizes 2500 - 9500
The coupling includes 5x elastomer segments
