SFC-035SA2

metal disc coupling for servo and precision drive applications.

• zero backlash
• high torsional stiffness
• low inertia
• single-flex and double-flex configurations
• misalignment accommodation
• clamp, keyway/setscrew and tapered-shaft-adaptor mounting options
• FEA-supported disc-element development

• Dimensions in mm unless otherwise stated.
• Standard bore diameter data per manufacturer tables.
• Standard shaft tolerance h7 (h6 or g6 designation B).
• j6/k6 optional tolerances with designations J/K only where supported by documented bore table.
• Bore-specific torque restrictions apply where shaft holding power limits rated torque.
• Maximum rotation speed does not account for dynamic balance.
• Torsional stiffness values are measurements for the element alone.
• Moment of inertia and mass are measured at maximum bore diameter.
• DB dimension qualification applies per manufacturer table notes.
• K = inner diameter of element.
• Where d2 exceeds K, shaft insertion is limited according to LF qualification.
• Clamping-bolt M interpretation follows manufacturer note.
• SFC-010 parenthetical dimensional qualification must remain attached to relevant table.
• Special bore arrangements require consultation with Miki Pulley.

• Manufacturer SFC portfolio passages describe different scope ranges: one passage cites maximum rated torque up to 8000 Nm and bore range up to 115 mm; an SFC-specific passage cites maximum allowable torque 250 Nm and bore range 3-45 mm. Do not merge these scopes.
• SFC is sold in the United States by Zero-Max under the ServoClass brand with product identity differences. No Zero-Max commercial relationship is asserted for Golden Bearing Company.
