Customer Reviews (4.8 / 5 · 5 reviews)

Violet A. ★★★★★

Installed this on my Sieg SC4 and the fit was perfect — no filing or adjustments needed to get the worm mesh right. My lathe is running quieter now with less backlash in the drive train.

Stella F. ★★★★★

The threads on this worm wheel are cut cleanly, and it seated onto the shaft without any filing or forcing. I had to shim the housing slightly on my SC4 to get the backlash right, but once dialed in it runs smooth and quiet.

Eli ★★★★★

The hardened worm gear teeth meshed with my existing lead screw smoothly right out of the box, and it took me under 20 minutes to swap the old part. I was worried about alignment, but the shaft slots fit perfectly into the bearings.
