NBK America now offers the XG Series of couplings. Why? TO keep pace with the evolution of servomotors.
Couplings today are a key component for helping servomotor-driven setups deliver speed-response frequencies … without the problem of vibration that usually accompanies such designs. In fact, it’s difficult to get maximum servomotor performance with high-rigidity couplings such as disc-type couplings.
So NBK’s high-gain rubber couplings (in the manufacturer’s XG Series) has properties that have evolved in tandem with servomotor evolution.
