Single Disc Coupling – High Rigidity Zero Backlash Coupling

The Single Disc Coupling is our high rigidity precision coupling product, featuring a single set of stainless steel disc + two flange hubs structure. This series follows the dimension conventions used by the major disc-coupling makers; stack height and bolt circle are confirmed per size. The disc design achieves absolute zero backlash and provides high torsional rigidity, suitable for medium to high speed, high precision positioning servo drive applications. Ideal for CNC machine tools, automation modules, precision positioning stages, and more.

Key Features

• Assembly Replacement – Direct replacement of existing same-type assemblies in customer equipment; custom bore machining available per customer drawings
• Absolute Zero Backlash – Rigid metal disc connection ensures no lost motion during forward/reverse operation, meeting high precision positioning requirements
• High Torsional Rigidity – Disc structure provides excellent torsional rigidity for fast transmission response
• Misalignment Compensation – Simultaneously compensates for axial, radial, and angular installation deviations
• All-Metal Structure – No wearing parts, no lubrication required, maintenance-free
• High Speed Capability – Excellent balance performance, suitable for high speed operation

Couplings have no cross-brand model codes, so select on torque and bore instead. Start from our cross reference overview.
