What does the grade of lubricating oil mean? Why do lubricants with the same grade number have different viscosities?
The grade of lubricating oil refers to the viscosity level. The viscosity measured at 40 degrees Celsius is classified into several grades; the higher the value, the greater the viscosity.
What does the grade of lubricating oil mean? Answer: According to ISO standards, industrial lubricants are classified into various viscosity grades based on the viscosity measured at 40°C. The higher the value, the greater the viscosity; therefore, the grade of a lubricant indicates its viscosity level. Why do lubricants with the same grade number have different viscosities? Answer: Each viscosity grade of lubricant has a specific range for its viscosity (which corresponds to the tolerance band in mechanical processing), typically ±10%. For example, the viscosity range for 100# gear oil is 90–110, while that for 150# gear oil is 135–165; any value within these ranges is considered acceptable.

Answer: According to ISO standards, industrial lubricants are classified into various viscosity grades based on the viscosity measured at 40°C. The higher the value, the greater the viscosity; therefore, the grade of a lubricant indicates its viscosity level. 2. Answer: Each viscosity grade of lubricant has a specific range for its viscosity (which corresponds to the tolerance band in mechanical processing), typically ±10%. For example, the viscosity range for 100# gear oil is 90–110, while that for 150# gear oil is 135–165; any value within these ranges is considered acceptable.
According to ISO standards, industrial lubricants are classified into various viscosity grades based on their viscosity measured at 40°C; the higher the value, the greater the viscosity.

Why do lubricants with the same grade have different viscosities? Answer: Each viscosity grade of lubricant has a specific viscosity range, typically within ±10%. For example, the viscosity range for 100# gear oil is 90–110, while that for 150# gear oil is 135–165; values within these ranges are considered acceptable.
The grade of lubricating oil is as follows: according to ISO standards, industrial lubricants are classified into various viscosity grades based on their viscosity at 40°C. The higher the value, the greater the viscosity; therefore, the grade of a lubricating oil refers to its viscosity grade. The reason for different viscosities of lubricants with the same grade is that each viscosity grade has its own range of viscosities (equivalent to a tolerance band in machining), usually ranging from ±10%. For example, the viscosity range for 100# gear oil is 90–110, while that for 150# gear oil is 135–165; any value within these ranges is considered acceptable.
