Unique-Bargains Helical Beam Coupling 5mm to 7mm 25mm Dia 30mm Length

SKU CH-6YR0-JG43Q

Connects 5 mm to 7 mm shafts with a 25 mm diameter aluminium helical beam coupling that absorbs misalignment and end-play

  • Zero backlash ensures precise motion transfer with a two-piece metallic spring design
  • Connects 5mm to 7mm shafts using 90 degree screw angle for secure fit
  • Spring action absorbs parallel, angular misalignment and shaft end-play
  • Aluminium alloy construction provides lightweight durability at 25mm diameter
  • 30mm total length suits encoders, lead screws, small pumps and feed rollers

Precision shaft coupling for light-duty drives

This aluminium-alloy helical beam coupling joins a 5 mm shaft to a 7 mm shaft with zero backlash. Its spring action absorbs parallel and angular misalignment plus end-play. It suits encoders, instrumentation, lead screws, small pumps and feed rollers needing torsionally flexible connection.

Check shaft sizes and mounting space

Verify both shafts measure exactly 5 mm and 7 mm diameter before ordering. Confirm the 25 mm outside diameter and 30 mm overall length fit inside your machine envelope. Ensure the 90-degree screw angle is accessible for tightening on your assembly.

Single coupling supplied in the box

The package contains one shaft coupling only; no extra fasteners, keys or lubricant are included. Plan to source any set screws, locking compound or alignment tools separately for installation.

Questions about this item

Does the 5mm to 7mm helical beam coupling come with mounting screws or must they be purchased separately?

The package contains one shaft coupling made from aluminium alloy with a 25mm outside diameter and 30mm total length; no screws are included.

How do I decide between the 5mm and 7mm bore options on this coupling?

The coupling connects a 5mm shaft on one side to a 7mm shaft on the other; choose it only when your application needs that exact bore combination.

What does the 90-degree screw angle mean once the coupling is installed on a machine?

The two set screws sit at right angles to each other, so tightening one does not interfere with the other and both bores clamp securely.
