نابض، ساعة، مطحنة منضدة كبيرة HiTorque

Fits my SX3.5's Z-axis fine feed perfectly, and the tension feels right straight out of the package. Took about ten minutes to swap in and now the quill returns smoothly every time instead of hanging up.

Wasn't sure I needed this until the quill return got sticky on my bench mill. Dropped it into the Z-axis fine feed assembly and now the quill snaps back smooth every time. Took ten minutes to install.

The quill pinion on my SX3.5 had a sloppy return for months until I swapped in this clock spring, and now the fine feed snaps back smooth every time. Coil tension feels right out of the package, no trimming needed.
