2. Hydraulic Linear Actuators – Use pressurized hydraulic fluid to produce motion. – Offer high force capabilities, ideal for heavy-duty applications.
3. Pneumatic Linear Actuators – Operate using compressed air. – Provide rapid movement and are commonly used in repetitive and high-speed applications.
Specialized Linear Actuators in Industry
special types:
1. Linear Axes with Several Rotating Plates – These systems combine linear motion with rotational capabilities, allowing for multi-axis movement within a single unit. – Commonly used in complex automation tasks where precise alignment and positioning are required, such as in robotics and CNC machining.
2. Vertical Axes and Holding Brakes as Clamping Elements – Vertical linear actuators are designed to move loads vertically, often used in applications like lifting, lowering, or vertically positioning components. – Holding brakes act as clamping elements, securing the actuator in place and preventing unwanted movement, crucial for maintaining safety and stability in vertical applications.
3. Linear Axes with a Position Measuring System – Incorporate sensors and feedback mechanisms to measure and report the position of the actuator with high accuracy. – Essential for applications demanding exact positioning and repeatability, such as in automated assembly lines and precision machining.
4. Linear Axes with Manual Steering and Digital Indicator Position – Combine manual control with digital readouts to provide real-time feedback on the position of the actuator. – Useful in scenarios where manual adjustments are necessary, but precise positioning and monitoring are still required, like in calibration and testing setups.
