An actuator is commonly referred to as a 'bullet actuator' based on its cylindrical shape resembling a bullet. While there isn't a strict technical definition for this term, it generally implies a compact and cylindrical linear motion device that operates similarly to other types of actuators but with a particular emphasis on its compact size and streamlined design. Bullet actuators typically feature a motor, lead screw, and housing encased in a cylindrical body, offering a combination of small form factor, high force output, and precise linear motion control. These actuators are often used in applications where space is limited, and a sleek design is desirable, such as in home automation, robotics, automotive, and medical equipment.
