What is the difference between No. 2 and No. 3 lithium based grease?

It's the difference between hard and soft.

No. 3 is just its NKGI number, that is, the penetration degree, No. 2 is at 265-295, the most commonly used, No. 3 is at 220-250, harder, and is generally used in applications that require resistance to water or solid impurities, reducing equipment wear.

A little harder, more by hand, 2 a little softer and harder, more with a machine filling, can also be applied by hand. There is no difference in performance.

3. According to the NLGI classification, the degree of taper penetration (needle penetration), the grease is from 000 to 6, the higher the number, the harder the grease. 2 is commonly used lubrication, 3 is used for the lubrication of heavy load or vertical motor bearings.

4. The consistency is not the same, that is, the needle edge, the high concentration is used for low-speed motors, such as 6 and 8 motors, No. 3 is generally used, and the low concentration is used for high-speed motors, and No. 2 is generally used for high-speed motors.

No. 3 is more viscous than No. 2.

Hello! Glad for your question. Universal Lithium Grease No. 2 is suitable for summer or winter

In winter, the temperature is low, choose a lower number, choose a large grade in summer, if you are not clear, you can choose 0 or 1, these two are omnipotent. Use No. 2 lithium grease will do. Lithium-based grease is made from natural fatty acids (stearic acid or 12-hydroxystearic acid) lithium soap, thickened with medium-viscosity mineral lubricants or synthetic lubricants, while synthetic lithium-based grease is made from synthetic fatty acid lithium soap, thickened.

1.Introduction of lithium lipids.

Lithium grease is an advanced grease that can be used as a high-speed bearing grease, a high-temperature splash grease, and a fully synthetic gear oil. The manufacturing process of lithium grease is mature, and its lubricating performance is very outstanding, and it is widely used in various industries.

2.The difference between lithium grease No. 1, No. 2 and No. 3.

Lithium grease No. 1, No. 2, and No. 3 refer to the three specifications of lithium grease, respectively. In terms of chemical composition, they are not very different, mainly in terms of performance parameters such as viscosity index, dehydration and oxidative stability.

3.Lithium grease No. 1.

No. 1 lithium grease has good performance in viscosity index, dehydration, extreme pressure, oxidation resistance and extremely low temperature performance, and is suitable for low-speed and heavy-duty or general industrial machinery lubrication.

4.Lithium grease No. 2.

No. 2 lithium grease is better than No. 1 lithium grease in terms of dehydration, oxidation resistance, and extremely low temperature performance, and is suitable for lubrication under high temperature conditions such as high-speed bearings, automatic transmissions, braking systems, and cylinder walls of internal combustion engines.

5.Lithium grease No. 3.

No. 3 lithium grease is better than No. 1 and No. 2 lithium grease in terms of high temperature resistance, extreme pressure resistance, oxidation resistance, dehydration and extremely low temperature performance. It is suitable for high-temperature and high-speed friction parts, heavy equipment gearbox lubrication and locomotive bearings and other high-demand occasions.

6.Precautions for using lithium greases.

When using lithium grease, it is important to note that mixing with other types of grease may reduce lubricating properties, so you should choose the same type of grease. In addition, care should be taken to prevent lithium lipids from entering the ** and eyes during the operation of the fingers.

7.Summary.

In general, lithium grease No. 1, No. 2, and No. 3 all have their own application occasions. When selecting lithium grease, it is necessary to select the corresponding specifications and models according to the actual needs, so as to achieve better lubrication effect.

No. 1, No. 2 and No. 3 lithium greases differ in their lithium content and the type and amount of additives used. Lithium-based grease refers to a grease that adds lithium soap as a base oil to lubricating oil, which is usually used in high-temperature and high-load mechanical equipment and bearing components to reduce wear and friction.

The further expansion and extension of the view or answer is that lithium celery traveler drain base grease has the advantages of high temperature resistance, water resistance, extreme pressure and wear resistance and good mechanical stability, so it is widely used in the suppression of defects. According to the different formulations and types of additives of lithium soap, lithium-based grease can be divided into different grades such as No. 1, No. 2, No. 3, etc. Among them, No. 1 lithium grease has the lowest lithium content, generally no more than 15%, which is suitable for low-speed and light-load bearings and friction pair components; No. 2 lithium grease has a lithium content between 25-35% and is suitable for bearings and friction components at medium speeds and loads; The No. 3 lithium-based grease has a lithium content of more than 40%, which is suitable for high-speed heavy-duty and high-load bearings and friction pairs.

In addition, different grades of lithium-based grease may also be added with different types and amounts of antioxidants, extreme pressure additives, anti-wear agents and anti-corrosion agents to meet specific application requirements.

In summary, the difference between No. 1, No. 2 and No. 3 lithium grease is the difference in lithium content and the type and amount of additives. The selection of the right lithium grease should be determined according to the use conditions and requirements of the specific machinery and equipment to achieve the best lubrication effect and maintenance effect. <>

Summary. Hello dear, I am happy to answer for you: Is No. 3 lithium grease a semi-liquid lubricant Reply as follows:

Lithium grease is suitable for the lubrication of rolling and sliding friction parts of various mechanical equipment in the temperature range of -20 120. No. 3 refers to the consistency of the grease No. 2 lithium grease: No. 2, that is, the amount of oil precipitation in the grease.

In terms of differences, the domestic No. 3 lithium grease and No. 3 lithium grease are not suitable for copper pipe transportation. No. 2 lithium grease, the more oil is divided, so do not mix it, it is better not to, the softer the grease is. In addition to the thickener, No. 3 lithium grease and No. 2 lithium grease have similar physical and chemical properties, 2. The dropping point is different, and it is mainly used for the lubrication of heavier load machinery.

Its performance, working environment, and index requirements are definitely different, and grease brands such as Krupp cannot correspond. No. 3 lithium grease and EP2 both belong to lithium grease (one is general lithium, you can buy the corresponding base oil directly, the smaller the number, their composition must be different,'. 3. The amount of oil is different, resulting in abnormal loss of the machine, is No. 3 lithium grease a semi-liquid lubricant?

Hello dear, I am happy to answer for you: Is No. 3 lithium grease a semi-liquid lubricant The reply is as follows: 3 lithium grease is suitable for the rolling and sliding friction parts of various mechanical equipment in the temperature range of -20 120.
