17 mm aluminium flexible shaft coupling

This aluminium-alloy flexible shaft coupling joins two 17 mm shafts with a 65 mm overall length and 45 mm outside diameter. It uses a clamp-type M6 fastening for secure attachment and weighs 216 g. The component is designed for servo motors, spindle drives and stepper motors where vibration absorption and torque transmission are required.

Clamp installation with M6 hardware

The coupling installs by tightening the integral clamp screws against each 17 mm shaft, requiring only standard hex tools. Ensure both shafts are clean, free of burrs and aligned within the coupling’s flexible element limits to avoid premature wear. Over-tightening the M6 screws can distort the aluminium hub, while excessive misalignment will reduce the elastic torque capacity and increase vibration.

Verify shaft diameter and space envelope

Confirm that both shafts measure exactly 17 mm and that the 65 mm by 45 mm envelope fits within your machine layout. Check that the clamp-style connection matches your torque and speed requirements, as the supplier specifies aluminium alloy construction with a silver-tone finish. No additional hardware beyond the supplied coupler is included.

Questions about this item

How can I verify the 17 mm bore coupling is transmitting torque without vibration after installation?

Run the servo or stepper motor at operating speed and listen for unusual noise; the aluminum-alloy flexible element is designed to absorb vibration so smooth, quiet rotation indicates it is working as intended.

What components are included in the package and what additional hardware is required?

The box contains one flexible shaft coupler weighing 216 g; you will need to supply two M6 clamp screws and ensure both shafts are 17 mm diameter.

Which bore combination should I select for a 17 mm motor shaft and a 17 mm driven shaft?

This model is a single 17 mm to 17 mm version with 65 mm length and 45 mm outside diameter, so it matches identical 17 mm shafts directly.
