Pololu Glideforce LACT12-500AL Industrial-Duty Linear Actuator with Acme Drive: 250kgf, 12" Stroke (11.5" Usable), 0.66"/s, 12V

The Glideforce Industrial-Duty Linear Actuators by Concentric International are robust 12V DC gearmotors designed for heavy-duty applications. They utilize either an acme screw drive or a ball screw drive to efficiently move a shaft along its length, maintaining position even when unpowered. The acme screw models can handle dynamic loads up to 250 kgf and static loads up to 450 kgf, while the ball screw models support dynamic loads up to 450 kgf and static loads up to 1360 kgf. These actuators feature built-in limit switches, an overload clutch, and a sealed case rated IP65 for protection against dust and water.

These actuators are ideal for applications requiring precise linear motion control, such as in industrial machinery, automotive systems, and robotics. The integrated limit switches ensure safe operation by halting the motor at each end of the actuator's range. This allows for reliable performance in environments where precision and durability are crucial.

One of the standout features of these actuators is their ability to reverse direction upon reaching a limit point by simply reversing the supplied voltage. This is facilitated by the integrated diodes. Additionally, the all-steel frame and extension tube provide structural integrity, making these actuators suitable for demanding environments.

Available in various stroke lengths from 10 cm to 60 cm, these actuators offer flexibility to fit specific project requirements. Optional potentiometers linked to the shaft position are available for feedback systems, enhancing the actuator's versatility in automated processes.

For easy installation, heavy-duty mounting brackets in machined aluminum or stamped steel are available, requiring two per actuator. A mounting clevis option is also offered to convert the actuator ends into a clevis-style connection, broadening the range of possible mounting configurations.

When testing or using the actuator, ensure that the extension shaft does not rotate relative to the actuator body to prevent misalignment. For electronic speed and direction control, a motor controller or driver is required. The actuators draw around 2.4 A with no load, but can exceed 13 A under maximum dynamic load, with a stall current of approximately 50 A at 12 V.

Actuators with feedback potentiometers include additional wires for position sensing, enabling precise control of the actuator's position. This feature is particularly beneficial in applications requiring accurate positioning and motion control.
