1.3KG high thrust 20mm 18 degrees M3 lead screw linear stepper motor with brass slider
This is a 20 mm stepper motor with a brass slider, and double linear bearings.
Double linear bearings can provide strong support to the slider, and this motor has about 1.3 KG of thrust (13N).
Due to the cost on brass slider, and linear bearings, this motor has higher cost compared to other linear stepper motors with a plastic slider.
The stroke/travel distance of this motor is about 34mm, if customers want longer/shorter lead screw/stroke, we have other models with different lead screw length.
We have 21mm/34mm/63mm stroke on 20mm linear motor.

About linear stepper motor with slider:
Our slider motor is a full set of assembly including motor + lead screw + bracket + slider.
Motor’s step angle is generally 18°/step, which means 20 steps for each turn.
When motor rotates one turn, slider moves one lead.
For single start lead screws: pitch =lead.
So the step length is (step length means linear movement slider travels, when the stepper motor take exactly one step):
Lead screw lead/steps of each rotation
For example if lead screw is M2*0.4P (0.4mm pitch regular M2 lead screw), step angle of the motor is 18°, step length of this motor is 0.4mm/20=0.02mm/step.
Also, lead screw length is customizable, and we also need to adjust bracket’s design, if you customize lead screw length.
Application of stepper motors:
Stepper motors are used for precise control, widely used on medical equipment, 3D printer, industrial precise control, automation equipment, etc.
Stepper motors can be used in any mechanisms requirement precise conrtol and rotational/linear movement.
Advantage of stepper motors:
Stepper motor can reach precise control even without close-loop encoders / without feed back system, also they do not have electrical brushed. Thus there is no electromagnetic interference and electrical sparks issues. In some cases, they can replace DC brushed motors/ brushless motors.
Stepper motors are easy to control with drivers, and this feature establish its important position in the field of precise control.
1. Precise control achievable, programmable
2. Without electromagnetic interference & electrical sparks
3. Small size
4. Reasonable price
5. Low noise
6. Long service life
