What is Hydraulic Oil Cylinder

Hydraulic cylinders play a key role in all hydraulic applications. They help transfer power between a pump and an actuator - or motor.
They have a wide range of applications and can be used in many different industries. They need to be lubricated with oil to keep them functioning.

Hydraulic cylinder oil is an oil that is used to lubricate the pistons, rings, springs, valve stems, and more. It is designed to protect these parts from damage by reducing friction between them and the cylinder wall.
The cylinder is one of the main components of an engine, and its operation is vital to its functioning. It is also a part of the fuel system, which can help to improve performance and efficiency.
These parts use a lot of energy to move, and that is why it is important to select an oil that will reduce friction and allow the engine to work more efficiently. An oil with low-viscosity will flow more easily through the engine, and the resulting lower oil pressure can help to reduce fuel consumption.

Hydraulic cylinders are used in many different industries, such as construction and mining ect. Their design is very targeted and can be applied to different scenarios and purposes。
Excavator cylinder
This type of oil cylinder is mainly used for micro excavators, small excavators and medium excavators, including stick oil cylinder, boom oil cylinder, bucket oil cylinder and bulldozer oil cylinder. The product has the characteristics of compact structure and high reliability
Milling machine oil cylinder
This series of oil cylinders is specially designed for the hydraulic system of the milling machine. The actions performed include belt tension, swing and lifting of the feeding belt, lifting of the scraper, control of steering and clutch, lifting of the side plate, lifting of the outrigger, etc. Special design is adopted to adapt to the characteristics of large vibration and dust when the main engine works, with high reliability and long service life.
Mining machinery
This series of oil cylinders are widely used in the hydraulic system of mining machinery such as mining machines, roadheader, etc., to perform the support, steering, lifting, tilting and other actions of the host machine. This series of oil cylinders has compact structure and safe and reliable operation.
Special vehicle oil cylinder
This series of oil cylinders are widely used in the hydraulic systems modified by dump trucks and road-clearing vehicles to perform lifting, steering, tilting, side shifting and other actions. This series of oil cylinders has reasonable structure, reliable operation and easy maintenance.
Oil cylinder of agricultural machinery
This type of oil cylinder is mainly used for supporting various agricultural machinery such as harvesters, tractors, balers, etc. The product has the characteristics of compact structure and high reliability.
Sanitation cylinder
This series of oil cylinders is designed for the hydraulic system of sanitation equipment, mainly supporting garbage transport vehicles, garbage compression stations, garbage incineration equipment, etc. Special design is adopted to meet the requirements of good corrosion resistance, high reliability and long service life of environmental sanitation equipment.

Besides,they also come in a variety of types, such as single and double acting cylinders. In single acting cylinders, one chamber is pressurised by the hydraulic fluid and this is what provides movement, in double acting cylinders both sides of the piston are pressurised.
The cylinder tube needs to be sealed at both ends, to prevent oil leaking and keep the pressure in. Seals can be made from a variety of materials, depending on the type of cylinder and what it is intended for.
Cylinders need to be highly resistant to wear and corrosion, as any cracks could scrape the seals and cause contamination to enter the system. This will lead to breakdown and a costly repair bill.
Synthetic hydraulic oils are chemically produced fluids that contain additives to enhance their physical properties. They offer a wide range of benefits, including superior performance at high temperatures and pressures, lubricity, oxidation stability, fire resistance, and biodegradability. However, they can be very toxic and are incompatible with some seal materials.
