Lubricating grease and lubricating oil are excellent lubricating materials, but because of their different characteristics, the use of different can not completely replace each other, summed up, the two main have the following differences:

Grease because of its components in thick solid agent there, giving the system a will not automatically flow thick ointment state for lubrication of the friction parts. When the mechanical movement parts in a static state, the grease has the ability to maintain its shape and not part of loss or dripping down from, when in a dynamic, is not due to the action of gravity or centrifugal force and leakage or splash, lubricating oil can not satisfy this requirement.

Grease viscosity with temperature changes than lubricating oil small, therefore the use of grease temperature range than that of lubricating oil wide, and grease adhesion than those on the lubricating oil good, smear on the metal surface or parts in the vertical placing or moving does not automatically loss, so in open or sealed undesirable friction parts and mechanical application is superior to lubricating oil.

Grease in mechanical friction parts of lubrication, when shear stress is increased, grease as liquid viscosity, flow will occur deformation, the characteristics of lubricating grease decided it has good lubrication and sealing door, and lubricating oil doesn't have this ability.

Grease because of its structure characteristics, with high voltage resistance, the use of long life, low consumption, lubrication equipment simple structure. The lubricating oil pressure of the poor, the lubrication of the parts need to be refueled frequently, but also a large amount of fuel consumption, if the fuel cycle, you need to seal system, lubrication equipment structure is relatively complex, and investment covers an area is larger. In addition the grease with buffer and the effect of reducing noise, and lubricating oil in this regard.
Grease for itself is solid or semi fluid state and in the lubrication surface of the starting torque is large, the similar viscosity is relatively large, poor liquidity, in the high-speed operation of the site as lubricating oil, in the high speed (10000r / min) cannot be used grease. And because of the high temperature phase change, and easy to oxidative deterioration, and grease the shift and heat radiation ability is poor, unlike the lubricating oil can be constantly strip away the friction surface due to wear and metal filings and other impurities, and the use range of the grease by certain restrictions.

Each have advantages in lubricating greases and oils compared. Grease under certain conditions is cannot replace lubricating oil, this is not be ignored, but in many working conditions, advantages and benefits brought by replacing the lubricating oil grease is undeniable.
Grease at room temperature is most semi solid material, but it does have a unique mobility, at ambient temperature and at rest as it can keep its own solid shape without flow, can not adhere to the metal slide. By force exceeds a certain limit at high temperature or when it can produce liquid flow. Grease by moving parts in mechanical cutting effect, it can generate motion and lubrication, reduce friction and wear between moving surfaces. When the shear action stops, it can restore a certain consistency. This special liquidity, decided it can not apply in parts of lubricating oil lubrication. In addition, because it is a semi solid material, the sealing effect and protective effect than good oil, grease and oil compared with the following advantages:

Grease the long service life, grease supply fewer, not always add, in difficult to frequent refueling of friction parts, use of grease lubrication more favorable. Some sealed bearings can filling amount of grease in the assembly, has been used in the end of the bearing life so far.
