Durable Nema 11 stepper motor has 10000 hours lifetime

Lead Screw Set, compact, large load carrying capability, rustproof and long service life.

Precise and accurate linear motion, large mechanical advantage.

T8 brass nut, with 4 holes for fixing to the machine.

Smooth, quiet, low friction,and low maintenance, very suitable for 3D printer z axis.

Widely used in 3D Printer, stepper motor, machine tools, and other equipment.

Material: Stainless Steel Lead Screw; Copper Nut; Lead Screw: Diameter: 8mm; Length: 100mm

Nut turn an around move 4mm

Copper nut, with 4 holes for fixing to the machine

Used on stepping motor driving guide rail,machine tool, and other equipment.

Fit for 3D printers, engraving machine, etc...

A must have for print quality and printer feel/function: It fixed a lot of bed leveling, 1st layer adhesion issue, prevent the one side bed sagging, is known to improve print quality as well as prevent issues with dual z axis rods going out of sync.

Compare with brass nuts, These nuts have a lot tighter fit than any brass nuts in the past and are dead silent.

Material: POM, it is a special Engineering plastic material, common name is"Saigang" which closed to the properties of steel, it is better then brass for a leadscrew. Even PRUSA is Using POM On their MK Series of printers.

POM is a tough and self lubricating plastic, will not squeak, and is pretty durable. installed these on an Ender 5 Plus, Stock lead screw caused a lot of noise, and they almost eliminated the problem had where Z gantry would go out of level.

Size: pitch 2mm lead 8mm, make sure you know the size of you rods before purchasing to avoid any returns.
