SUNGIL SDS Single Disk Coupling, Aluminum (OD 12-104.5 mm)

SUNGIL SDS Single Disk Coupling, Aluminum (OD 12-104.5 mm)

Single disk coupling with stainless steel plate springs between high strength aluminum alloy hubs. Backlash-free full metal design with high torsional stiffness and a short overall length for precise positioning.

Key features

  • Stainless steel plate spring absorbs misalignment with zero backlash
  • High static torsional stiffness for servo and stepping motors
  • Set-screw, side-clamp (cylinder or flange, low inertia) and hub-split versions
  • Flange/cylinder shapes; cylinder type identified by suffix D after the bore
  • Alternative screw finishes: electroless nickel (NI/ASS) or stainless (SUS/ASS)
