Pololu Glideforce LACT4-500APL Industrial-Duty Linear Actuator with Acme Drive and Feedback: 250kgf, 4" Stroke (3.5" Usable), 0.66"/s, 12V

The Glideforce Industrial-Duty linear actuators are robust 12V DC gearmotors designed for high-performance applications. Utilizing acme or ball screw drives, these actuators can handle dynamic loads up to 450 kgf (1000 lbs) and static loads up to 1360 kgf (3000 lbs). They feature a sealed steel frame for protection against dust and water (IP65 rated), and include integrated limit switches and an overload clutch for enhanced safety and longevity.

These actuators are ideal for applications requiring precise linear motion, such as robotics, industrial automation, and adjustable machinery. With a variety of stroke lengths ranging from 10.2 cm to 60 cm, they offer flexibility for different project requirements. The optional potentiometer feedback system allows for accurate position tracking, making them suitable for closed-loop control systems.

One of the standout features of these actuators is their ability to maintain position even when unpowered, thanks to the acme screw drive. This makes them particularly useful in situations where maintaining a static position is critical. Additionally, the ball screw drive versions provide higher efficiency and load capacity, catering to more demanding applications.

The actuators are equipped with a 25 cm cable with stripped wire ends for easy integration. For those with feedback, additional wires are included to connect the potentiometer, enabling precise position feedback. Heavy-duty aluminum or steel mounting brackets and a mounting clevis are available to facilitate secure attachment to various structures.

When using these actuators, it's important to prevent the extension shaft from rotating during operation to avoid misalignment with the limit switches and potentiometer. A motor controller or driver is recommended for managing speed and direction, with options like the Jrk G2 24v21 Motor Controllers for feedback-equipped models.
