مقعد، زنبركي

The SKU number on the package matched my existing part exactly, so swapping in this spring was completely hassle-free. It feels identical in tension to the original, which is exactly what I needed for my lathe's cross-slide.

This spring seated perfectly into the tailstock assembly on my bench mill, no filing or fussing needed to get the SKU 2151 to align. It’s a solid little OEM part that feels sturdier than the generic ones I’ve tried before, and my quill return is snappy again.

Installed this spring on my mini lathe's tailstock and it snapped right back into place — much smoother than the old worn-out one. The tension feels spot on for the job.
