Penelope M. ★★★★★ Oct 22, 2026

Exactly the right fit for my SC4 lathe—the 10 mm bore lined up perfectly with my shaft. The 42 mm overall length matched the old part without any adjustment needed. Nice to have a precise replacement that feels solid and works smoothly.

Jacob ★★★★★ Oct 21, 2026

Replaced the worn shaft on my lathe and the 42mm length lined up exactly with the original. The 10mm bore slid onto the spindle without any slop, so the handwheel turns smooth again.

Richard ★★★★★ Oct 20, 2026

The fit is spot-on for the SC4—the 10mm bore slid right onto the shaft without any wobble. I measured it and the 36mm nut dimension matches the original part exactly. Solid little piece for the price.
