Tech Drawing


The Bullet Series 50 Cal. Linear Actuator was developed to have a slim in-line motor design. Includes built-in hall effect sensor, which allows for synchronization, position and speed control. The hall effect feedback is vital to applications where multiple actuators must travel in sync. Popular within robotics, manufacturing, marine, off-road vehicles and home automation.

To move between two and four actuators in synchronous we recommend our dedicated control board, the FA-SYNC-X. A video tutorial of how to use this product is available here

CAD models of this actuator can be found under Resources/3D Files. For further information review the specifications and technical drawings down below or visit our tutorials page for instructions on how to use this actuator with switches, remotes, speed controllers, and Arduino. 

Accessories sold separately include: Remote Controls - Switches - Micro-Controllers - Power Supplies 

We offer them as standard in 12v or 24v, two force options, and in stroke lengths from 6 to 40 inches
