Precautions for Use

In case of mounting on D-cut shaft, be careful about the position of the D-cut surface of the shaft. ⇒Mounting and Maintenance
There are sizes where the hex socket head bolt exceeds the hub outer diameter of the coupling and the rotating diameter is larger than the hub outer diameter. Please be careful of the interference of coupling.

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

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

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

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.
