Solid build, slightly tight bore

The coupling is very sturdy. Had to polish the shaft slightly to get it to slide on smoothly, but once installed it holds tight. Good value.

Great for corrosion resistance

We use these in wet environments. The 304 stainless holds up well against moisture. Exactly as described in the specs.

Perfect fit for my hydraulic pump

Installed this on a replacement motor shaft. The keyway aligned perfectly and the stainless steel quality is top notch. No vibration issues so far.

Reliable connection

Been running this setup for 3 months now. No slippage and the set screws remain tight. Highly recommend for rigid connections.

Good standard coupling

Does the job well. Shipping packaging could be better to prevent scratches, but the product itself is undamaged and functional.
