Pololu Glideforce LACT18-500AL Industrial-Duty Linear Actuator with Acme Drive: 250kgf, 18" Stroke (17.5" Usable), 0.66"/s, 12V

The Glideforce Industrial-Duty Linear Actuator is a robust and efficient solution for moving heavy loads with precision. Designed for industrial applications, this 12V DC gearmotor utilizes an acme screw drive to move a shaft along its length, holding its position even when unpowered. It can handle dynamic loads up to 250 kgf and withstand static loads up to 450 kgf. Featuring limit switches for safe operation, an overload clutch for protection, and an IP65-rated sealed case, this actuator is built for durability in demanding environments. Available in various stroke lengths, it offers options with or without feedback potentiometers for enhanced control.

Perfect for applications requiring precise movement, these actuators can be used in automation systems, lifting mechanisms, or any setup needing controlled linear motion. The integrated limit switches ensure the motor stops safely at the end of its range, while the overload clutch prevents damage from excessive loads.

With its all-steel construction and sealed design, the actuator is protected against dust and water, making it suitable for outdoor or challenging industrial settings. The actuator's ability to hold its position without power adds an extra layer of reliability, reducing the need for constant power supply.

For enhanced flexibility, heavy-duty mounting brackets made from aluminum or stamped steel are available, allowing for secure attachment to various structures. Additionally, a mounting clevis can be used to convert the actuator ends into a clevis-style, offering more mounting options.

To control the actuator, connect it to a 12V power source, ensuring the shaft does not rotate relative to the body during operation. Reversing the voltage will change the direction of motion. For electronic speed and direction control, a motor controller or driver is essential, with options available for both feedback and non-feedback models.

These actuators are designed to handle a stall current of around 50 A at 12 V, though they typically draw less during normal operation. It's important to account for potential current spikes during abrupt starts or changes in direction, which can be managed with acceleration-limiting features available on many motor controllers.

Overall, the Glideforce Industrial-Duty Linear Actuator is a reliable choice for those needing a powerful and adaptable linear motion solution in industrial applications.
