This high-torque hybrid linear stepper motor is built to tackle demanding applications, combining the reliability of a NEMA17 frame with a compact 42mm design. Its 1.8° step angle ensures precise linear motion, making it ideal for tasks requiring accurate positioning—from industrial automation to heavy-duty DIY projects.​
What sets it apart is its high torque output, delivering the power needed to drive heavy loads or overcome resistance in rigorous workflows. Whether you’re operating conveyor systems, precision lifts, or automated machining tools, this motor maintains consistent performance under pressure.​
Choose between Tr6 (6mm diameter) and Tr8 (8mm diameter) trapezoidal lead screws to match your specific needs: Tr6 offers a streamlined profile for space-constrained setups, while Tr8 provides enhanced durability for high-stress applications. Both options ensure smooth, low-friction operation, reducing wear and extending service life.​
Perfect for users seeking a balance of power, precision, and flexibility, this linear stepper motor adapts seamlessly to diverse environments—from factory floors to custom robotics. Upgrade your system with a motor that delivers high torque without compromising on accuracy.
