High-Gain Rubber Type Coupling XG2

This suppresses servo motor hunting and greatly shortens settling time. New NBK coupling XG2. Exhibits even higher responsivity than metal disk couplings. Contributes to improving productivity, such as suppressing speed unevenness during stepper motor operation.

About Shaft Couplings

This page introduces flanged shaft couplings. It provides a clear introduction to the features and structure of flexible shaft couplings, fixed shaft couplings and rubber shaft couplings.

Choosing the most suitable coupling

We also explain the basic points for selection of the "perfect couplings" to meet customer needs. If you have struggled with selecting the perfect coupling from the many available, this is a must-see.

About Couplings

Coupling is a component used to connect a drive shaft and a driven part, for example, a motor shaft and a ball screw for the purpose of transmitting the torque.
