Works well for lead screws
Make sure to measure your shaft diameter accurately before ordering. Once installed, it works smoothly with my lead screw setup.

Sturdy build quality
No vibration noticed during operation. The anodizing looks professional and the set screws hold firmly. Highly recommend for servo applications.

Great precision for CNC
Used this on my CNC router spindle. The keyway fits perfectly and there is no vibration at high speeds. Very satisfied with the build quality.

Good value but tight fit
The coupling is sturdy and well-made. It was slightly tight on the shaft initially but settled in after use. Good value for the price.
