👉 A load fluid, often used in hydraulic systems, is a type of liquid that carries the force or load applied to a component within the system. It's typically incompressible and has high viscosity, which allows it to efficiently transmit power and maintain consistent pressure across the system. Load fluids are crucial for ensuring smooth operation, reducing wear and tear on mechanical parts, and providing stability in hydraulic actuators, brakes, and other machinery. Common load fluids include mineral oils, silicone oils, and synthetic fluids, each chosen based on the specific requirements of the application, such as temperature range, load capacity, and environmental conditions.
