PRODUCT DESCRIPTION
This is a flexible motor coupling that can connect a driving shaft to a driven shaft and efficiently eliminate any misalignment. It also has minimal backlash, which is an advantage of this flexible coupling OD:20mm x L:25mm Bore: 5x10mm.
This flexible coupling has an outer diameter of 20mm and a length of 25mm and is made of machined aluminium.
The screws that clamp the shafts should be tightened securely, but not excessively. These clamping couplings will not damage the shafts.
It has a spiral cut along its length that makes it flexible enough to fit two shafts that are not perfectly aligned and reduce binding effects. This type of coupling is also called a beam coupling, a helical coupling, or a flexible coupling.
Some of the important features of flexible shaft couplings are:
– The helical cut makes them act like springs in the X, Y, and Z linear axes, but not in the rotational axis. This means they do not increase backlash, so they are suitable for precision CNC work.
– A coupling is a device that transmits power and torque. Couplings usually do not allow shafts to disconnect during operation. However, some couplings can slip or disconnect when the torque exceeds a certain limit.
– By selecting, installing, and maintaining couplings carefully, you can save money by reducing maintenance costs and downtime.
– It can protect the driving and driven shafts from harmful effects caused by misalignment, shock loads, shaft expansion, or vibrations.
Features:
- Corrosion resistance and High Durability
- One-piece construction with long-lasting performance
- Torsional stiffness: Zero backlash
- Low moment of inertia offering constant velocity

How to Use Flexible Coupling OD:20mm x L:24mm Bore: 5 x 10mm
Slide the coupling onto the two shafts, ensuring each bore fully covers its respective shaft (5 mm and 10 mm). Align shafts within a few degrees or tenths of a millimeter, then tighten each clamp screw evenly until the coupling is snug—avoid over-torquing to prevent screw or shaft damage. Verify alignment under low-speed rotation before ramping up to operational RPM.

Frequently Asked Questions
What maximum rotational speed can this coupling handle?
This helical coupling supports speeds up to 20,000 RPM, making it suitable for high-speed stepper and DC motor applications.
Can I use this coupling with a 5 mm motor shaft and 10 mm leadscrew?
Yes, the dual-bore design clamps securely onto a 5 mm driving shaft and a 10 mm driven shaft without additional adapters.
How tight should I fasten the clamp screws?
Tighten each screw evenly until the coupling grips the shaft firmly but do not exceed finger-tight plus a quarter-turn with a small hex key to avoid stripping or deforming the aluminum.
