These curves are obtained based on the test conditions of our company’s drive. The nema 17 hybrid linear stepper motor performance will vary under different drive conditions. To improve motor reliability and lifespan, it is recommended to control the load within 50% of the motor’s thrust.

| Linear Stepper Motor Lead Screw Customization

Choose your end-machining style below (threaded, plain, or bespoke) and match it with our lead screw specification table. Please contact technical support to confirm precise dimensions based on the screw diameter.

The specifications listed are standard references. All parameters—including diameter, lead, and especially screw length—can be fully customized to your requirements. Unsure about the selection? Contact Our Engineers for a bespoke solution.

| Custom Nut Solutions for External Nut Linear Stepper Motor

We offer a wide range of standard and non-standard nut customizations to meet your specific load, precision, and space requirements. Our technical team can engineer bespoke nut geometries and materials to fit your unique design.

Please note: The smaller the nut backlash, the higher the positioning accuracy. However, this also increases internal friction, which may lead to higher resistance and a corresponding reduction in effective thrust.

Optimizing your linear drive requires a balance between precision and mechanical efficiency. Choose the ideal nut material and geometry to match your specific load, speed, and accuracy requirements.

POM (Polyacetal) Nut – The Precision Favorite

• Recommended Match: NEMA 6, 8, 11, 14, 17

• Key Features: High wear resistance, low noise, and high transmission efficiency.

• Application: Currently the most popular choice for precision instruments. It is ideal for compact motors with light loads that require smooth, high-efficiency motion.

Steel Nut – The Ultimate Durability

• Recommended Match: High-load applications or extreme environments.

• Key Features: Superior strength, exceptional corrosion resistance, and heat tolerance.

• Application: Ideal for vacuum environments, medical sterilization (autoclave), or chemical processing equipment. It handles significantly higher axial loads than brass and offers maximum service life in harsh conditions.

Brass Nut – The Heavy-Duty Workhorse

• Recommended Match: NEMA 17 and above

• Key Features: Superior rigidity; can withstand loads several times higher than engineering plastics.

• Application: Designed for industrial applications requiring high load capacity and structural stiffness.
