What hydraulic oil additives reduce friction?

Certain hydraulic oil additives can be used to reduce friction in hydraulic systems. These additives are designed to improve the oil’s lubricating properties and reduce wear on system components. Some common examples of friction reducing additives used in hydraulic fluids include:

1. Anti-wear additives: These additives form a protective film on the metal surface to reduce friction during operation. They often contain compounds such as zinc dithiophosphates or zinc dialkyl dithiophosphates.
2. Friction modifiers: These additives change the surface properties of hydraulic system components to reduce friction. They often contain organic compounds such as molybdenum disulfide or graphite, which create a low-friction barrier between surfaces.
3. Extreme Pressure (EP) Additives: These additives are specifically designed to protect hydraulic systems under high loads and temperatures. They often contain sulfur or phosphorus compounds that form a protective layer on the metal surface, reducing friction even in extreme conditions.

It is important to note that each hydraulic system has different requirements and specifications regarding the type and amount of additives used. Therefore, it is important to refer to the manufacturer’s recommendations and guidelines when selecting hydraulic oil additives to reduce friction.
