Samuel ★★★★★

The clearance on this sleeve is tight enough to eliminate any wobble I was getting on the Z-axis, and it slid right on without needing to force it. Machining the brass worm gear was spot-on, so the lead screw meshes smoothly now.

Abigail M. ★★★★★

The sleeve fit perfectly onto the worm shaft of my bench mill, and the precision machining is noticeable—no wobble at all. Replaced the old worn part in under ten minutes, and now the Z-axis runs smooth and quiet again. Exactly what I needed to keep the mill running like new.

Evelyn I. ★★★★★

Had a small issue with the original sleeve causing some play, but this replacement fits tightly and cleaned up the Z-axis movement nicely. The machining on it looks precise and matched up perfectly with the worm shaft threads on my SX3.5.
