20mm Lead Ball Screw Kit With Nut, End Supports, Flexible Coupler, Nut Housing And Nema 34 Motor Bracket For Precise CNC Motion, 1320mm (51.97in) Long, SFE2020 RM2020
✔️ 1320mm (51.97in) long, 20mm lead screw with BK15/BF15 end supports
This precision 20mm lead ball screw kit is built for CNC motion systems. It pairs a high-lead ball screw with a metal deflector nut, BK15/BF15 end supports featuring an integrated motor bracket for Nema 34 motors, a flexible coupling, and a nut housing. The setup keeps the motor shaft, coupling, axial bearing holes, and screw axis in strict alignment for accurate, sturdy, and quiet travel. Typical uses include CNC routers, mills, and automated axes where precise linear motion matters.
