What is the difference between lube oil and hydraulic oil?

lube oil is a special oil that can form a smooth and lube protective layer on the surface of industrial machines and other equipment to reduce the wear of equipment during friction. lube oil can be used at different temperatures and pressures, and different additives can be added as needed to achieve different functions and performance. The scope of lube oil application is very wide, such as property protection, tool maintenance, car maintenance, aircraft and helicopter maintenance, etc.

Hydraulic oil, also known as hydraulic cylinder or pressure oil, is a special lube oil used to transmit power and control the movement of the machine. Hydraulic oil generally requires stable transmission under conditions such as pressure, flow and temperature to ensure the normal operation of the equipment. The most widely used field of hydraulic oil is mechanical equipment, such as excavators, cranes, smelting equipment, injection molding machines, etc.


1. Different functions

lube oil is mainly used to reduce friction between machine parts to prevent wear and failure of parts and ensure the normal operation of equipment. Hydraulic oil is mainly used to transmit machine power and control the movement of the machine so that the machine can operate normally.

2. Differences in chemical composition

There are many types of lube oil additives, and different additives can be added according to the needs of different fields. The additives of hydraulic oil are mainly manganese, molybdenum, phosphorus and sulfur, which are used to prevent wear and erosion.

3. Different use conditions

lube oil can be used at different temperatures and pressures, so its application range is very wide. Hydraulic oil generally works under high pressure and high temperature conditions, so its application range is relatively narrow.

4. Different viscosity grades

The viscosity grades of lube oil and hydraulic oil are also different. The viscosity grade of lube oil is generally between negative 10 and positive 30, while the viscosity grade of hydraulic oil can reach positive 200.


Applications of lube oil and hydraulic oil:

lube oil is mainly used to relieve friction between machine parts and can be widely used in various fields, such as automobiles, aircraft, ships, metallurgy, electricity, petrochemicals, machinery and other industries.

Hydraulic oil is mainly used for force transmission and control of machines, and is often used in various mechanical equipment, such as cranes, excavators, injection molding machines, machine tools and railway locomotives. Hydraulic oil plays a vital role in these equipment, not only speeding up work efficiency, but also ensuring the normal operation of equipment.
