Compared with lubricating oil and grease has the following advantages

Compared with lubricating oil, grease has the following advantages:

1. Compared with lubricating oil with relative viscosity, grease has more bearing capacity and stronger vibration absorption ability.

2. Because of the digestion and absorption effect of the thickener structure management system, grease has a lower volatilization rate. Therefore, in the case of grease lubrication, especially in high temperature and long cycle operation, grease has stronger characteristics.

3. Because of the capillary action of the thickener structure, the price of base oil of grease tends to be smaller than that of lubricating oil with relative viscosity.

4. Grease can produce a grease ring with a certain sealing effect, which can avoid the invasion of solid or liquid pollutants, and is beneficial to the application in wet, cold and dusty natural environment.

5. Grease can firmly adhere to the lubricated surface, even in the skewed or vertical surface does not flow. It deforms under pressure and flows like oil; Once the external force is removed, it restores to the original condition, stopping the flow. Thus, grease can work on an open or poorly sealed friction member.

6. With grease can simplify the formulation and maintenance of machinery and equipment, can eliminate the oil lubrication system software often must be gasoline pump, cooling tower, oil separator, and so on, thus saving the cost of machinery and equipment.

7. Because the grease has good adhesion and is not easy to flow out, it can still maintain satisfactory lubrication after restarting after shutdown. 8 with grease usually only a small amount of grease to rub the lubricated surface, so it can greatly save the amount of refined oil. This is undoubtedly extremely important in light of the current shortage of electricity and energy.

Just because grease has the above advantages, so grease and grease lubrication more and more of our attention. About 80% of the world's roller bearings choose fat lubrication, rolling bearings also have 20% with fat lubrication, even the reducer has always been lubricated with edible oil, at this stage, there are a lot of development trend toward the Angle of fat instead of oil.

Defects: grease also has disadvantages, mainly poor refrigeration heat discharge characteristics, relatively large internal friction resistance, grease for grease is not as convenient as oil, so its use suffers from certain restrictions.
