Hydraulic components are essential parts of hydraulic systems that use pressurized fluid to transmit power and control machine movement. Common components include hydraulic pumps, motors, valves, cylinders, filters, and accumulators. Each component performs a different function, such as generating pressure, controlling oil flow, converting hydraulic energy into mechanical movement, or protecting the system from contamination. These components are widely used in construction machinery, agricultural equipment, mining machines, industrial production lines, and other heavy-duty applications.
