Designed for use in the main spindle shaft on CNC machining centers, the Miki Pulley ALS-SGN coupling uses unique taper-lock hubs. This hub design ensures concentricity and rotational balance during high speed operation.
The ALS-SGN coupling’s high torque elastomer center element absorbs resonance and mitigates conductive heat while providing over 22,000 Nm/rad torsional stiffness. The coupling’s aerodynamic profile decreases noise at high speeds.
Another important feature of the Miki Pulley ALS-SGN coupling is its ease of installation design. Taper-lock hubs slip easily onto the two connecting shafts and the coupling is locked into position with recessed tightening screws. Basic ALS-SGN coupling specifications are:
• Maximum RPM: 22,000
• Maximum transmittable torque: 810 Nm (597 ft-lbs )
• Ambient operating temperature: -40 C-120 C (-40 F – 248 F)
