Excellent industrial grade

Fit perfectly on my compressor motor. The keyway alignment was precise and the steel feels very robust. Highly recommend for heavy duty use.

Solid steel construction and works as expected. Shipping took a bit longer than anticipated but the product quality makes up for it.
