  • Power Rigid Coupling

Taper Shaft Type

Compatible with taper shaft servomotors

Apply φ11 taper shafts and adaptors for φ16 taper shafts.

RoHS compliant

The Power Rigid Coupling has no flexible element, so it cannot absorb misalignment. Please use this series for applications where secure centering is available.

Taper Shaft Type


High Torsional Stiffness
Does not have a flexible structure, this type has high rigidity.
Secure Coupling
The adoption of the taper lock system allows for larger shaft coupling force.
No Backlash
There is no backlash due to the friction of the coupling through a taper-lock.
Compact & Low Moment of Inertia
The axial length is maximally reduced, allowing for more compact design. Also provides lower moment of inertia through the polygonal outer ring configuration.
