For SaleNEW ****4.75 INCH TRAVEL 3.5 "(inches) width Z AXIS FOR CNC ROUTER**** This design eliminates the coupling There is a adjustable belt mechanism, to tighten the belt to the stepper motor pulley.To be used as a Z axis for CNC Router, Plasma Cutter, 3D Printer, Automation Projects and many more. The slide is manufactured using strong aluminum aircraft alloy 6061T. The lead screw is Precision 3/8-12 Acme (Trapezoidal e) type supported with bearings at both ends for rigidity. *******************************Precision Acme threads VS Threaded rod : Why is acme rod good? ACME rods are built to tolerance specifications. Regular threaded rod is not. ACME was designed for linear motion. Threaded rod was designed for tightening things together. Threaded rod has alot of variance because it does not hinder its intended use by having the variance. Also since threaded rod has so much variance, the accompanying nuts for the threaded rod have alot of play. ACME nuts have much better tolerance and are repeatable. ) ************************* We use ACETAL Delrin® NUT 3/8-12. (Extra nut on demand .) 4 Linear Delrin Bearings are used to move the slide easily and smooth. It will accept Nema 23 size stepper motor. Back plate dimension 0.250"x 11"x3.5" Front plate dimension0.250"x3.5" x 3" Distance between holes 1"(0.5"symmetrical from center)... Screws are M5-0.8 countersunk0.5" from bottom and top Lead screw is secure with a lock-nut 1/4x20, no axial play. Rods are 1/2 C1045 quality precision groundThe assembly use anti-rust socket head cap screws M5-0.8Shaft is machined flat to proper hold the timing belt pulley. We recommend that same for the shaft stepper. PACKAGE CONTENTS:1 Z AXIS1 BELT 2 PULLEY 1 TOP PLATE FOR ATACHING THE STEPPER
