1. No. 1, No. 2 and No. 3 are just its NKGI number, that is, needle penetration. No. 2 is 265-295 and is commonly used. No. 3 is 220-250 and is harder. It is generally used in applications that require resistance to water or solid impurities to reduce equipment wear.
2. 3# is harder and is mostly applied manually. 2# is slightly softer and harder. It is mostly filled by machine and can also be applied manually. There is no difference in performance.
3. According to the NLGI classification, cone penetration (needle penetration), grease ranges from #000 to #6. The larger the number, the harder the grease. #2 is commonly used for lubrication, and #3 is used for lubrication of heavy loads or vertical motor bearings.
4. The viscosity is different, that is, the needle mouth. High concentration is used for low-speed motors, such as 6, 8-level motors, generally using No. 3, and low concentration is used for high-speed motors, generally No. 2.
Summary: The difference between lithium-based grease No. 1, No. 2 and No. 3 is their hardness. As for which one is better, No. 1, No. 2 and No. 3, they are all equally good, but because of their different hardness, they are suitable for different degrees of mechanical lubrication.
