Works as described

No complaints here. Installation was straightforward with the included clips. Deducting one star only because the instructions were minimal, but it's easy to figure out.

Robust industrial component

Exactly what I needed for a custom automation rig. The steel feels heavy-duty and the finish protects against rust in our workshop environment.

Good quality, slightly stiff initially

Great build quality for the price. It was a bit stiff out of the box, but after applying some grease to the nipples, it moves very smoothly.

Perfect fit for my lathe project

The 20mm bore was exact, and the keyway aligned perfectly without any need for filing. Solid construction and smooth operation even at higher RPMs.

Reliable coupling

Been running this for three weeks straight on a test bench. Zero play and no overheating. Highly recommend for anyone needing a 20mm single-key joint.

Excellent value

Used this to connect a motor shaft to a conveyor drive. No vibration issues and handles the torque well. Free shipping was a nice bonus.

5 FAQ

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

A: For optimal longevity and safety, we recommend operating this coupling at speeds up to 3000 RPM depending on the specific load and angle of operation.

Q: Does this come pre-greased?

A: The joint comes with a light factory coating for protection, but we strongly recommend injecting high-temperature lithium grease via the grease nipples before first use.

Q: Is this compatible with a metric 20mm shaft with a 6mm keyway?

A: Yes, this unit is designed specifically for a 20mm bore with a standard single-key configuration suitable for most metric applications.

Q: Are replacement retaining clips available separately?

A: Yes, replacement clips are available in our store under the 'Coupling Accessories' section, or you can source standard DIN 471 clips locally.

Q: Can I return this if the bore size is wrong for my setup?

A: Absolutely. As long as the item is unused and in original packaging, you can return it within 30 days for a full refund or exchange.
