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

The Glideforce Industrial-Duty linear actuators by Concentric International are robust 12V DC gearmotors designed to move a shaft back and forth using either an acme screw drive or a ball screw drive. These actuators maintain their position even when unpowered. The acme screw versions can handle loads up to 250 kgf and withstand static loads up to 450 kgf, while the ball screw versions can manage dynamic loads up to 450 kgf and static loads up to 1360 kgf. Equipped with limit switches for safe operation, these actuators can reverse direction when the supplied voltage is reversed, thanks to integrated diodes. An overload clutch is built-in to prevent damage from excessive loads. The durable design features an all-steel frame and extension tube, with a sealed case rated IP65 for dust and water resistance.

These actuators are perfect for applications requiring precise linear motion, such as in industrial automation, robotics, and vehicular systems. The ability to hold position without power makes them ideal for tasks where maintaining a specific position is crucial, even during power outages.

The Glideforce actuators offer significant advantages, including high load capacity and robust construction. The availability of different stroke lengths and optional feedback potentiometers allows for customization to fit specific needs. The versatility in design ensures compatibility with a wide range of applications, providing reliable performance in demanding environments.

The actuators come with a range of mounting options, including heavy-duty brackets made from machined aluminum or stamped steel, and a mounting clevis for converting actuator ends into a clevis-style. These accessories enhance the flexibility of installation, making it easier to integrate the actuators into various systems.

For those seeking advanced control, the feedback versions of the actuators can be paired with motor controllers like the Jrk G2 24v21 for precise positioning. The non-feedback versions can be controlled using simple motor controllers, offering straightforward integration into existing systems.

Overall, the Glideforce Industrial-Duty linear actuators provide a powerful and reliable solution for heavy-duty linear motion applications, backed by a design that ensures durability and precision.
