✔️ GCr15 shaft, 10mm pitch, 2150mm stroke, EF20 mounts, 14mm coupler

You will notice immediate improvement in your milling station with this anti backlash linear assembly. Builders swap these rolling thread replacements to eliminate mechanical play and tighten feed rates. You gain reliable axial control that handles heavy side loads without wandering off center.

✅ C7 precision threads maintain tight tolerances during heavy side cuts ( 0.98 in)
✅ Custom length shaft runs 2150mm or 84.65in total travel for wide CNC bed installs
✅ 10mm pitch offers precise feed increments matching small stepper motor steps
✅ Including 14mm motor bore adapter eliminates extra spacer hardware requirements

💡 What makes a precision ball screw assembly handy for upgrading manual milling machines?
Standard gear racks often chatter under load, so rolling element upgrades solve that problem. - Rolled thread manufacturing guarantees repeatable lead accuracy for complex contour passes - Zero play operation prevents sudden table jumps when reversing spindle movement - Compatible EF20 brackets slide easily onto common T slot rails for quick installation
