Good but check sizing
Works well overall. Just make sure you measure your shaft diameter accurately before ordering. I had to exchange for a slightly larger size, but support was helpful.

Reduced Vibration
Noticeable improvement in surface finish on my milled parts after switching to these spider couplings. The elastic element absorbs misalignment perfectly.

Solid Construction
Very high quality for the price. The set screws hold tight and I haven't experienced any slipping during high torque operations. Shipping was fast too.

Perfect for CNC Upgrade
Installed this on my lathe spindle and the vibration is significantly reduced. The aluminum feels very sturdy and the anodizing is smooth. Highly recommend for hobbyist CNC machines.
