Linear Stepper Motor Actuators

Linear stepper motor actuators create motion in a straight line rather than the circular motion provided by conventional stepper motors. They are widely used in medical devices, lab automations and semi-conductor industries. GEMS provides a wide range of capative, non-capative and external type of stepper motor linear actuators and various sizes of ACME thread lead screws and trapezoidal metric lead screws. With such a wide catalog of products and experience in manufacturing motors, it becomes easier for us to deliver quality products. Our stepper motor linear actuators come in six standard sizes, NEMA 8, 11, 14, 17, 23 and 34 with a variety of external nuts, anti-backlash nuts and ball screws. You can choose from our standard screw lengths or order your custom one. Our designs are compact and optimized for silent operation. Due to the large scale of our operations in China, we are able to provide inexpensive linear stepper motors for your products.

Here at GEMS Motors, we understand the importance of quality parts for your products and strive to deliver the best quality possible. Our linear motors are designed to be durable and robust, with minimum failure rate.

1.8° 42mm (NEMA17)  Linear Stepper Motor Actuators

Our Nema 17 linear steppers have large selections of travel-per-step, ranging from 0.00012 inch (0.003mm) to 0.005 inch (0.127mm).  The finer resolutions are available by using microstepping or a 0.9° stepper. External, capative and non-capative linear versions are available for this frame size. These linear actuators can generate up to 50 lb (25 kg) thrust force and 100mm/s speed.
