Needed different bore size

My fault for measuring incorrectly. The product is fine, but make sure you check your shaft diameter before ordering.

Good quality but tight fit

Material is solid and well machined. Had to use a bit of force to get it on the shaft, but once installed it is very rigid.

Excellent rigidity

No backlash observed during operation. Great for applications requiring high coaxiality between shafts.

Perfect for my CNC spindle

Fits perfectly on my motor shaft. The stainless steel feels very durable and the set screws hold tight without slipping.
