NBK Flexible Couplings — vibration-absorption capable disk type

By Leave a Comment

The vibration-absorption capable disk type XGHW-C has a dynamic vibration absorber on the high rigidity disk. It enables vibration absorption and use of higher gain levels when compared to regular disk types, thereby also allowing a shorter stabilization time. The vibration absorption function reduces the amount of parameter adjustment work, and lowers the time required […]

Couplings for special environments

By Leave a Comment

NBK provides couplings that can be used in special environments such as clean room, vacuum, high temperature (80 ° C or higher) are available. ● Low particle The amount of attached particle is ultra low. This is directly available in a cleanroom. This does not bring contaminated matters into a cleanroom. ● Vacuum-supported A material […]

XGT2 high-gain rubber type coupling: productivity and stabilization time

By Leave a Comment

High-gain flexible coupling which surpasses XGT-CXGL-CXGS-C in performance. This is a single-piece construction with the two aluminum hubs molded with high-gain rubber. The optimal damping and rigidity design enables realization of even greater servomotor gain, leading to reduced stabilization time. Technical information⇒Productivity and stabilization time Suppressing speed unevenness control during stepping motor operation is effective.⇒Suppressing […]

NBK’s new XGHW-C flexible couplings

By Leave a Comment

 This video showcases NBK’s new XGHW-C flexible coupling. These flexible couplings feature vibration absorption function added to high rigidity couplings. Additionally, this coupling has a structure with both high rigidity and vibration absorption. The individual dynamic vibration absorbtion is separate from the inertial rotor and elastic body in order to achieve vibration absorption. NBK […]
