Hydraulics are used in manufacturing to transfer and control energy in the form of a pressurized fluid, usually oil, to accomplish tasks such as movement, force and power transmission. Some specific examples of how hydraulics are used in manufacturing include:
- Power transmission: Hydraulic systems can be used to transmit power from a power source, such as an electric motor, to operate machinery and equipment. This can include things like presses, lift trucks and excavators.
- Movement: Hydraulic systems can be used to control movement in applications such as robotics, factory automation and in machine tools.
- Force: Hydraulic systems are used to generate large amount of force to accomplish tasks such as lifting, pressing and clamping. They can also be used to control and apply force in applications such as presses and stamping machines.
- Position control: Hydraulic systems can be used to control and maintain the position of machine components and equipment. This can include applications such as die casting machines and plastic injection molding machines.
- Actuators: Hydraulic actuators are widely used to convert fluid pressure and flow into mechanical motion. These actuators can be designed in different forms such as linear, rotary and other special actuators.
- Lubrication: Hydraulic systems can be used to lubricate machinery, this can help to reduce wear and increase efficiency of the machines.
Hydraulics has become an integral part of modern drive and control techniques and is extremely suitable for regulating linear and rotating movement, both for large forces and precision movement with speed.

- Reliability: Hydraulic systems are reliable and have a long life expectancy if they are designed and maintained properly.
- Remote Control: Hydraulic systems can be controlled remotely using electrical or electronic devices, which makes them very convenient to use.
- Low maintenance: Hydraulic systems require relatively low maintenance.
What are the disadvantages of hydraulics?
There are several disadvantages of hydraulics, including:
- Leakage: Hydraulic systems can leak fluid, which can be messy and can lead to environmental damage.
- Vulnerability to contamination: Hydraulic systems are vulnerable to contamination by dirt, dust and other particles, which can cause damage and reduce efficiency.
- Complexity: Hydraulic systems can be complex and require a certain level of expertise to design, install and maintain.
- Limited flexibility: Hydraulic systems are limited in terms of the types of movement they can produce and the speed and precision of the movement can be affected by the size and complexity of the system.
- Temperature sensitivity: Hydraulic fluids can be sensitive to temperature changes and the system may not function properly in extreme temperatures.
- Flammability: Some types of hydraulic fluids are flammable and can pose a fire hazard if not handled properly.
- Weight: Hydraulic systems can be heavy and bulky, which can make them difficult to move or install in certain applications.
- Safety issues: If not properly maintained, hydraulic systems can pose safety risks such as leaks, explosions and other accidents.
- Limited power transfer: Power transfer capacity is limited in hydraulic systems, making them less suitable for high-power applications.
