But, actually there are some points customers are overlooking.
It is the evolution of Coupling technology that utilizes the linking of a Motor and an Actuator.
In using standard coupling technology, you may not be getting optimal performance from your Servo System.

Generally, the couplings used for a Servo System require flexibility and torsional rigidity.
To fulfill these technical specifications, the Slit Coupling was utilized during the 1990s and then updated to Disk Coupling in the 2000s.
Around 2005, the servo motor with a higher speed response frequency appeared.
There was a technological limit in regards to the shortening of the production cycle time even if we increase the coupling’s torsional rigidity.

The cause is co-vibration. The increase of a coupling’s rigidity is insufficient to increase the rigidity throughout the whole servo system.
Due to the high-speed response frequencies, the co-vibration of the Servo System cannot be avoided.
So what can be done?

The solution is to provide higher capacity for absorbing the vibrations that are a result of the higher speed response frequencies.
We propose High-Gain Rubber Couplings “XG series.”
We focused a rubber’s ability to absorb the vibration.
We succeeded to realize both the coupling’s rigidity and vibration reduction by an innovative molding technique within the internal structure.
