What is included in the kit?

A NEMA34 stepper motor, a 1500mm ball screw, a dual-rail carriage assembly and the mounting frame. Motor drivers and controllers are not part of it.

Will it fit my CNC router?

It mounts to existing frames through a bolt pattern, but you need to check your frame width and mounting holes against the actuator's footprint before ordering.

What driver does the NEMA34 motor need?

A stepper driver rated for the motor's current, plus a power supply sized for it. A small driver from a NEMA17 or NEMA23 setup will not run it.

Is a ball screw better than a belt for this axis?

For heavy loads and tight repeatability, yes. A ball screw resists back-driving and play better than a belt, at the cost of speed and more careful alignment.

Can it run vertically?

A ball screw holds position better than a belt under gravity, but check the motor's holding torque against the weight of your Z axis before relying on it.

Our take on the NEMA34 Stepper Motor Kit & Heavy Duty Ball Screw

This is a preassembled linear actuator: a NEMA34 stepper motor driving a 1500mm ball screw along a dual-rail carriage on an integrated frame. It is built for CNC routers and laser cutters that need a straight, repeatable push under load. The dual rails and ball screw resist flex and play during fast direction changes, which is the main selling point over a single-rail belt or lead screw axis. It suits builders upgrading a heavy table who want a bolt-on axis rather than a parts list.

Pros

Ball screw drive resists play under load
Dual rails hold alignment through fast reversals
Integrated frame stiffens the axis
Preassembled and ready to bolt to a frame
1500mm travel suits large tables

Cons

NEMA34 motor needs a matching high-current driver and supply
Long ball screw needs proper support to avoid whip at speed
Heavy assembly to mount and align
No motor driver or controller included

About the NEMA34 Stepper Motor Kit & Heavy Duty Ball Screw

This kit combines a NEMA34 stepper motor with a 1500mm ball screw and a dual rail assembly. It is a preassembled ball screw linear actuator that moves a machine table along a straight path.

The ball screw mechanism is built to limit play under load. The double rail design is meant to keep travel aligned and reduce flex during rapid direction changes. An integrated frame holds firm when running thick steel plates.

The actuator is made to mount directly onto existing frames and fits CNC routers and laser cutters.

Motor: NEMA34 stepper motor
Ball screw length: 1500mm
Guides: Dual rail assembly
Type: Preassembled ball screw linear actuator
Compatibility: CNC routers, laser cutters
