Rod-style linear actuators excel at lifting and thrusting applications, with thrust-bearings built into the actuators themselves. These devices are typically used in positioning equipment, CNC machines, and anywhere else slow point-to-point movement is required. Screw-driven linear actuators are suitable for low speeds, heavy loads, and high-inertial loads.
#COMPANIES USING ATUTOR WINDOWS#
Common applications for belt actuators include automated windows and doors, high-speed data acquisition, and scanning devices. Having of a basic understanding of the typical use-cases for the various types of electromechanical linear actuators may be a good starting point.īelt-driven linear actuators are designed for high speeds and light loads, and are suitable only for low-inertial loads. Please note that standard components – including the types of drive screws, motors, front and rear attachments, controls, and limit switches used – will allow for desired customization without the costs typically associated with special modifications. What's more, actuators featuring both modular design and open architecture enable interchangeable internal and external components, according to specifications. Depending on type and manufacturer, today's electromechanical linear actuators can handle loads up to 3,000 pounds (13 kilonewtons) and deliver speeds up to 100 inches/second (2540 millimeters/second), with strokes ranging from 2 inches (50 millimeters) to 60 inches (1,500 millimeters).Īctuators can be self-contained in aluminum, zinc, or polymer housings and ready to mount for easy plug-in operation (using either AC or DC power supplies). These devices serve as practical, efficient, and relatively maintenance-free alternatives to their hydraulic or pneumatic actuator counterparts.
Regardless of end use, an actuation system is designed by first identifying basic needs, then evaluating certain key parameters that ultimately affect the overall system operation.Įlectromechanical linear actuators are designed to provide precision, efficiency, accuracy, and repeatability in effecting and controlling linear movement. When a system is tailored for an application, the specific requirements will influence both the design and the manufacturing processes. With the availability of so many manufacturers, models and options, selecting the right linear actuator for your application can be a daunting task. Manufacturers throughout the world offer innumerable models of linear actuators in a wide variety of stroke sizes, speeds, voltage and types. Typical use cases include medical beds, patient lifters, wheelchairs, adjustable tables and workstations, and diagnostics, to name a few.Įach linear actuator application has unique requirements. Linear actuators are used in a variety of applications across numerous industries, including medical equipment, agriculture machinery, high-voltage switch gears, train and bus doors, and factory processes and assembly machinery.
