Product Description


The SM20-35L is a precision screw motor with a 0.4mm pitch between the output shaft and screw. The screw rotation generates thrust while being supported by the screw mechanism. With a basic step angle of 18 degrees, the motor completes 20 steps per revolution, achieving a displacement resolution of 0.02mm for precise control. The actuator uses subdivision drive mode to meet various application requirements.
Our team brings over 10 years of experience in stepper motor design, development, and production. We offer custom product development and auxiliary design services tailored to your specific needs. Your requirements drive our efforts - please don't hesitate to contact us!
