NBK Reliable high response coupling

: Flexible coupling High gain rubber type XG2 series

 

The story behind the XG Series

In accordance with the evolution of servomotors,coupling needs have changed as well.

Servomotor speed response frequency has improved drastically over the past few years, creating an environment prone to vibration : it is difficult to achieve maximizing servomotor performance with existing high- rigidity couplings (disk-type).

The " High gain Rubber Coupling XG Series ", with properties evolvng in tandem with servomotor evolution, is the ideal servomotor coupling.

 

 

 

Structure

• Integrated combination of alminum hub and high gain type rubber.

• Zero Backlash. 

 

 

 

 

Characteristics

• High gain servomotor reduces stabilization time.

• Suppressing speed unevenness during Stepping Motor Operation.

• They have excellent vibration absorption.

• Actuator drive noize reducible.

• High Torque.
