365mm T8 Tr8x8 Z Axis Lead Screw with Anti Backlash Spring Loaded Brass Nut Z-axis Upgrade Kit 8mm Lead for Ender 3 V2/ V2 Neo/Ender 3 Pro/Ender 3/Ender 3 Neo/Voxelab 3D Printer

Packing list: 1 * T8x8 365mm lead screw 1 * Anti backlash spring loaded brass nut(flange cutted) The lead of the thread is 8mm, which means that the nut will move 8mm if the nut turns one circle. The advantages of the lead screw are: Large load carrying capability Compact Large mechanical advantage Precise and accurate linear motion Smooth, quiet, and low maintenance, very suitable for 3D printer z axis. Minimal number of parts So this lead screw is very suitable for 3D printer Z axis, such as Ultimaker and Prusa i3. The screw type of this lead screw is ACME thread. ACME Threads are generally stronger than square threads due to their trapezoidal thread profile, which provides greater load-bearing capabilities.

• Lead screw diameter 8mm, length 365mm, SUS304 stainless steel. Anti backlash spring loaded brass nut, flange cutted, with 2 M3 threaded holes for fixing to the machine. The distance of the 2 holes is 18mm.
• Screw pitch: 2mm; Number of Thread/Start:4; Lead: 8mm (pitch*thread=lead)
• The Lead Screw is compatible with Ender 3 V2/Ender 3 V2 Neo/Ender 3 Pro/Ender 3/Ender 3 Neo/Voxelab 3D Printer.
• Dual Z-axis Upgrade: The update of the double z axis reduces the layer ripple caused by Z-axis vibration, making the structure more stable and improving the accuracy of 3D printers.
• Anti backlash spring loaded nut can provide higher accuracy when it moves up and down.
