A machined aluminium flexible shaft coupler for connecting a 5mm shaft to an 8mm shaft. The spiral-cut design provides slight flexibility to accommodate minor misalignment between shafts, reducing binding without introducing rotational backlash — making it suitable for precision CNC work.

Key Features

  • Flexible Spiral Cut – Accommodates minor shaft misalignment while maintaining rotational precision
  • Zero Backlash – Flexible in X/Y/Z linear axes but rigid in rotation, suitable for CNC applications
  • Double Set-Screws – Two set-screws per side for secure shaft attachment
  • Machined Aluminium – Lightweight and durable construction

Specifications

  • Shaft Size 1 – 5mm
  • Shaft Size 2 – 8mm
  • Material – Machined aluminium
  • Set-Screw Size – 2mm Allen key (hex wrench)
  • Set-Screws – 4 total (2 per side)

Ideal For

  • Connecting stepper motors to lead screws
  • CNC machines and 3D printers
  • Robotics and precision mechanical assemblies
