As a coupling manufacturer, NBK has found success in the field of precision miniature shaft couplings. From the technical development of single piece slot coupling, we have successfully developed all stainless steel coupling. At that time, the NBK coupling was a good match for the control motor and our market share rapidly increased. We continue to develop jaw, bellows, disk and other products to meet customer requirements, and develop peripherals such as servo motors, stepper motors and encoders. We focus on high frequency response, preventing fluctuations, improving gain, reducing stability time, and zero backgap. Therefore, NBK has developed the XG series high gain rubber type coupling based on * control theory, which has been introduced as a new generation of couplings in the motion control industry.
