Aluminum silicone insert couplings produced by Bervina to transmit torque between two shafts with no backlash.
The silicon insert (40 ShA) is positioned between the driving and the driven hubs that separates the two side of the coupling electrically. These anti-vibration couplings are available with set screws or clamps for fixing them on the shaft and can be used in the temperature range of -50 °C to 150 °C during operation.
