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 is designed for complete assembly interchangeability with single disc couplings from brands such as BIKON, R+W, and KTR. 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

Custom Manufacturing Available

Standard ball screws and linear guides don't always fit your design. Here's what RFU MOTION can customize based on your drawings:

  • Shaft end machining — machined precisely to your drawing
  • Screw length — cut to your exact requirement
  • Preload — light, medium, heavy, or custom value
  • Nut type — standard flange, special shape, or non-standard mounting interface
  • Rail length — continuous cutting with end finishing (chamfer or grinding)
  • Mounting holes — special thread sizes, hole spacing, or countersunk dimensions

Send us your drawing or specs — we'll deliver exactly what you need.
