Model: Nema 17 Non-Captive Stepper Motor Linear Actuator With Lead Screw-JK42HSC (1.8 degree)
External mechanical components separate from the motor are introduced into the design to keep the lead screw from rotating. The lead screw moves back and forth axially by restricting its rotation, which then drives the device it is attached to back and forth.
Flexible and compact linear actuator with 42 mm flange. The threaded nut is injection molded into the hollow shaft and comes with a trapezoidal or an ACME thread. Please refer to the accessories list for matching lead screws.
NEMA17, Non-captive linear stepper motor actuators, High performance, Exceptional endurance, Low noise, Highly effective. Multiple options: different size of motors, different types of leadscrews, different types of nuts.
Lead screws are often used in stepper motor actuators, for a cost-effect, easy-to-use linear motion solution. But stepper motors can also be used to drive ball screws.
A lead screw is sometimes referred to as a “power screw” or a “translation screw”. They are used within motion control devices to transform rotary or turning movements into linear movements.
A lead screw turns rotary motion into linear motion combining a screw and a nut where the screw thread is in direct contact with the nut thread. In the case of roller screws, the rollers rather than the nut are in direct contact with the screw thread offering greater efficiency.
