Long stroke linear actuators are devices used to convert rotational motion into linear motion over a relatively long distance. They are commonly used in various applications where linear movement is required, such as in industrial automation, robotics, medical equipment, and automotive systems.
The term “long stroke” refers to the length of the linear movement that the actuator can achieve. While the exact definition of a long stroke can vary depending on the context, it generally implies a longer distance compared to standard linear actuators. Long stroke linear actuators typically have a stroke length ranging from several inches to several feet, allowing them to cover a significant distance.
Long stroke linear modules can be powered by various mechanisms, including electric, hydraulic, or pneumatic systems. Electric actuators are one of the most common types and are often powered by DC motors. They consist of a motor, a gearbox, and a lead screw or a belt drive mechanism to convert rotary motion into linear motion.
The advantages of long stroke linear modules include:
1. Extended Range: Long stroke actuators can cover larger distances, making them suitable for applications that require extended linear movement.
2. Precise Positioning: These actuators are capable of achieving accurate and precise positioning due to their longer stroke length.
3. Simplified Design: Using a long stroke actuator can simplify the overall system design by eliminating the need for additional mechanisms or components to achieve the desired linear movement.
4. Flexibility: Long stroke linear actuators can be used in a wide range of applications due to their versatility and adaptability.
Common applications of long stroke linear modules include:
1. Conveyor Systems: They are used to move materials along a production line or warehouse.
2. Automated Machinery: Long stroke actuators can be used in various industrial automation processes, such as assembly lines, packaging, and material handling.
3. Robotics: They are employed in robotics applications that require extended linear movement, such as robotic arms or CNC machines.
4. Medical Equipment: Long stroke actuators can be used in medical devices for patient positioning, adjustable beds, or motorized wheelchairs.
5. Aerospace and Automotive: They find applications in aircraft and automotive systems for functions like seat adjustments, cargo handling, or wing flaps.
When selecting a long stroke linear actuator, consider factors such as load capacity, speed, accuracy, power requirements, and environmental conditions to ensure it meets the specific requirements of your application.
