軸套，X 軸進給螺桿

Installed it on my SX2.7 and the X-axis feed screw finally stays true instead of wobbling. The shoulder seats perfectly against the housing, so the alignment issue I'd been chasing is just gone. Exactly what the mill needed.

After swapping out the old bushing, the X-axis feed screw on my mini-mill now turns with noticeably less resistance. The fit was precise and it slid right into place without any binding, which was my main concern.

Noticeable difference in the smoothness of the X-axis travel once this was seated on the left end of the feed screw. Alignment feels spot on now, no more slight bind at the far end of the table. Fit was snug going on but that's what you want here.
