James ★★★★★

The 8mm bore fit perfectly on my 3501 mill's Z-axis, replacing the old coupling that had developed play. It's a solid little piece of metal for the price.

Sophia ★★★★★

Bolted this onto the 3501's Z-axis without any fuss—the 8mm bore on both ends lined up with the ball screw and motor shaft perfectly on the first try. It's a solid little part that does exactly what it's supposed to do, and it's reassuring to have the correct clearance fit rather than guessing with

Julian ★★★★★

The 25 mm length fit perfectly on the Z-axis ball screw of my 3501 mill, and the clearance bore meant no fiddly press-fit drama on install. Swapped out the old worn coupling and the axis is tracking smooth again, solidly made for the price.
