Tsubaki's Power Rigid Coupling is a rigid coupling for machine tools. It employs a taper-lock structure to ensure a more reliable connection. The Power Rigid Coupling has no flexible element, so it cannot absorb misalignment. Please use this series for applications where secure centering is available. ・Applicable shaft diameter :Φ16mm~Φ48mm Features ・Compatible with straight shafts and taper shaft. Compatible with taper shaft servomotors. Apply Φ11 taper shafts and adaptors for Φ16 taper shafts. ・Secure Coupling The adoption of the taper lock system allows for larger shaft coupling force. ・High Torsional Stiffness Does not have a flexible structure, this type has high rigidity. ・Non-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.
