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

| A | 98 Sh A | red | TPU | 0.4 - 0.5 | -30°C to +100°C | high damping | ||
| B | 64 Sh D | green | TPU | 0.3 - 0.45 | -30°C to +120°C | high torsional stiffness | ||
| C | 80 Sh A | yellow | TPU | 0.3 - 0.4 | -30°C to +100°C | very high damping | ||
| D* | 65 Sh D | black | TPU | 0.3 - 0.45 | -10°C to +70°C | electrically conductive | ||
| E | 64 Sh D | beige | Hytrel | 0.3 - 0.45 | -50°C to +150°C | temperature resistant | ||
The values of the relative damping were determined at 10 Hz and +20˚ C.
