氣壓彈簧轉換套件

Installed this on my mini mill and the head now moves so smoothly, no more fighting with that stiff torsion spring. The whole kit had everything I needed, no extra trips to the hardware store. It's made tramming the head a quick, one-handed job.

The torsion spring always fought me when adjusting the head height, but this kit replaces that whole headache with a smooth air cylinder. Everything I needed was in the box, and the column support feels rock solid now.

The torsion spring on my mini mill always fought me when I adjusted head height, but after this conversion the head glides smoothly and stays put exactly where I set it. The kit's hardware and air spring feel solid, and installation took me an afternoon without any surprises.
