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.
