Linear Actuators

Our 12 V linear actuators have dynamic load ratings ranging from 22 to 110 pounds and can be used in a variety of heavy-duty applications. Limit switches at each end make the actuators easy to control over their full ranges of motion, and an optional feedback potentiometer enables closed-loop position control.

They are available in a range of stroke lengths and speeds:

Pololu item #: 2268
Price: $49.95
Quantity:

This NEMA 17-size hybrid bipolar stepping motor has an integrated 28 cm (11″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).
