Exactly as described

Needed a variable diameter connection for a motor shaft adaptation project. This fit both shaft sizes perfectly with no wobble. Highly recommend for industrial applications.

Good value for money

Does the job well for connecting mismatched shaft diameters. Installation was straightforward. Just ensure you torque the set screws correctly to avoid slippage.

Great corrosion resistance

Using this in a slightly humid environment and the 304 stainless steel shows no signs of rust after three months of continuous operation. Very satisfied.

Solid build quality

The stainless steel feels very robust and the machining is precise. I deducted one star only because the set screws could be slightly longer for deeper grip, but overall a great product.

Perfect for my CNC retrofit

This rigid coupling solved my alignment issues perfectly. The extended length provided the necessary clearance, and the set screws held firm under high torque without slipping.

5 FAQ

Q: What is the maximum RPM rating for this adapter?

A: Due to its rigid and balanced construction, this coupling is rated for speeds up to 4000 RPM, depending on the specific shaft diameters used.

Q: What are the available bore size combinations for this variable diameter coupling?

A: This specific model supports dual bores ranging from 6mm to 20mm. Please check the selection dropdown for the specific combination you need before ordering.

Q: Is this suitable for outdoor use?

A: Yes, the 304 Stainless Steel construction provides excellent resistance to weather and corrosion, making it suitable for most outdoor industrial environments.

Q: Can this coupling handle misalignment between the motor and the shaft?

A: No, this is a rigid coupling designed for precisely aligned shafts. For applications with angular or parallel misalignment, we recommend our flexible jaw or beam couplings instead.

Q: Are the set screws included with the coupling?

A: Yes, the package includes high-grade alloy steel set screws pre-installed in the coupling body.
