Aluminium and stainless steel flexible diaphragm coupling, 32mm diameter, 30mm length, 9.5mm to 6mm bore

Unique-Bargains

Unique-Bargains 9.5mm to 6mm Bore Flexible Diaphragm Coupling 32mm x 30mm 10000RPM

SKU CH-1NC4-Q28WB

Connects 9.5mm and 6mm shafts up to 10000 RPM with 2.8 to 5.6 N.m torque capacity in a 32mm aluminium and stainless steel body

  • Connects mismatched 9.5mm and 6mm shafts directly
  • Handles 2.8–5.6 N.m torque for reliable power transfer
  • Spins up to 10000 RPM without vibration
  • Compact 32mm diameter fits tight assemblies
  • Aluminium and stainless steel resists wear long-term

Precision Motion Coupling

The Unique-Bargains flexible diaphragm coupling joins two misaligned shafts in precision motion systems. Its 9.5 mm to 6 mm bore range suits small-diameter motor and encoder shafts. The single diaphragm design transmits torque while absorbing parallel and angular misalignment. This component fits robotics, automation and light industrial drives.

Torque and Speed Rating

The coupling handles a continuous torque range of 2.8 N.m to 5.6 N.m at up to 10000 RPM. Aluminium alloy hubs and a stainless steel diaphragm provide the stated torsional stiffness. Exceeding either the torque band or the speed limit will cause premature fatigue. Select this part only when your application stays within both boundaries.

Sustained Load Behaviour

Under continuous operation the diaphragm flexes repeatedly without the backlash found in jaw or bellows types. Heat buildup remains low because the single metal disc has minimal hysteresis loss. Vibration stays controlled as long as shaft alignment stays within the coupling's rated misalignment envelope. The unit is not suited for shock loads that exceed the upper torque figure.

Questions about this item

What does the 10000 RPM rating mean when the coupling is installed in a real machine?

It is the maximum safe rotational speed; running the coupling above 10000 RPM risks mechanical failure, so the driven shaft must stay at or below this limit in operation.

What interface standard does the 9.5 mm to 6 mm bore follow, and what does it cap in practice?

The bores are plain cylindrical holes sized at 9.5 mm and 6 mm with no keyway or standard flange; they accept any matching shaft up to those diameters and transmit up to 5.6 N·m of torque.

What physical space and shaft sizes are needed to fit and mount this coupling?

The coupling measures 32 mm in outside diameter and 30 mm in length, and it requires one 9.5 mm shaft and one 6 mm shaft for the two bores.
