Pololu Glideforce LACT8-500AL Industrial-Duty Linear Actuator with Acme Drive: 250kgf, 8" Stroke (7.5" Usable), 0.66"/s, 12V

The Glideforce Industrial-Duty Linear Actuator is a robust 12V DC gearmotor designed for heavy-duty applications. It features an acme screw drive capable of moving loads up to 250 kgf (2500 N) and a static load capacity of 450 kgf (4500 N). With a stroke length of 20.3 cm (usable 19.1 cm), it operates at speeds up to 1.7 cm/s. The actuator's steel frame and extension tube, along with an IP65 rating, ensure durability and protection against dust and water.

Ideal for industrial automation, agriculture, or robotics, this actuator excels in environments demanding high force and reliability. Its built-in limit switches prevent overextension, while integrated diodes and an overload clutch enhance safety by reversing direction and protecting against excessive loads.

The actuator's ability to hold its position without power and its compatibility with feedback systems make it versatile for precise control applications. Optional potentiometers provide position feedback, enabling integration into complex systems where precise movement is crucial.

For easy installation, heavy-duty mounting brackets in aluminum or steel are available, requiring two per actuator. A mounting clevis can also be used to convert the actuator ends into a clevis-style attachment, offering flexibility in mounting options.

When using the actuator, ensure the extension shaft does not rotate to prevent misalignment. It can be controlled using a 12V power source, with direction controlled by reversing the voltage. Motor controllers or drivers are recommended for electronic speed and direction control, with options available for both feedback and non-feedback versions.

The actuator's stall current at 12V is approximately 50A, with typical usage drawing significantly less, around 2.4A with no load and up to 13A at maximum dynamic load. Acceleration limiting features in motor controllers can help manage current spikes during sudden starts or direction changes.

For actuators with feedback, the Jrk G2 motor controller offers precise control, simplifying setup with pre-configured settings. Calibration is necessary to ensure full stroke control, especially near the extremes of the range due to limit switches.

Overall, the Glideforce Industrial-Duty Linear Actuator is a reliable choice for applications requiring robust performance and precise control, with a range of mounting and control options to suit various needs.
