Pololu Glideforce LACT4-1000BL Industrial-Duty Linear Actuator with Ball Screw Drive: 450kgf, 4" Stroke (2.8" Usable), 0.66"/s, 12V

The Glideforce Industrial-Duty linear actuators are robust 12V DC gearmotors designed for heavy-duty applications, featuring ball screw drives for superior efficiency and load capacity. With a dynamic load capacity of up to 450 kgf and a speed of 1.7 cm/s, these actuators are engineered to hold positions even when unpowered. They are equipped with built-in limit switches, diodes for direction reversal, and an overload clutch for protection. The all-steel construction and IP65 rating ensure durability and resistance to dust and water.

The industrial-duty actuators are ideal for applications requiring precise and powerful linear motion. They can be used in automated systems, robotics, and other industrial machinery where reliable and repeatable movement is crucial. The ability to withstand static loads up to 1360 kgf makes them suitable for heavy lifting and positioning tasks.

The Glideforce actuators offer significant benefits, including their ability to maintain position without power, making them energy-efficient for static applications. Their robust construction ensures longevity in demanding environments, while the optional feedback potentiometers provide enhanced control for applications requiring precise positioning.

These actuators are available in various stroke lengths from 10.2 cm to 60 cm, catering to different application needs. The optional feedback potentiometers linked to the shaft position enable integration into feedback systems for applications that require precise control over movement.

Mounting options include heavy-duty brackets made from machined aluminum or stamped steel, allowing for secure attachment to structures. A mounting clevis is also available to convert actuator ends into a clevis-style, providing versatility in installation.

To operate, connect a 12V power source to the actuator's motor leads, ensuring the output shaft does not rotate relative to the actuator body. Reversing the voltage changes the direction of motion. For electronic speed and direction control, a motor controller or driver is necessary. The actuators have a stall current of approximately 50 A at 12V, with typical usage drawing significantly less.

The actuators come with a 25 cm cable ending in stripped wires. Models with feedback potentiometers include additional wires for position sensing, allowing users to determine actuator position by reading voltage changes.
