What is SAE J2360?
SAE J2360, which has its roots in military lubricant specifications dating back to the 1940s, emerged in the late 1990s and was updated in 2012 to ensure that it kept pace with the needs of the marketplace.
What do numbers mean on gear oil?
The number indicates a level of the oil viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity. Viscosity of gear oils designated with a number only without the letter “W” (SAE 80, SAE 90, SAE 140 etc.)
What is the SAE grade?
The SAE number (also known as “viscosity rating” or “viscosity grade”) is a code to grade motor oils by their viscosity characteristics. The SAE viscosity grade is not the actual viscosity value of the motor oil. Originally, viscosity ratings were monograde — meaning it was only one number (like engine oil SAE 30).
What does API GL 5 mean?
The designation API GL-5 denotes lubricants intended for gears, particularly hypoid gears, in axles operating under various combinations of high-speed/shock load and low-speed/high-torque conditions. The performance specifications for API GL-5 are defined in the most recent version of ASTM D7450.
What is MIL PRF 2105E?
MIL-PRF-2105E. Sulfur in Petroleum Products (High-Temperature Method)
What are the two SAE viscosity grades?
Two series of viscosity grades are defined in SAE J300: (a) those that contain the letter W and those that do not contain the letter W. Single-viscosity-grade oils (“single-grades”) with the letter W are defined by maximum low-temperature cranking and pumping viscosities and a minimum kinematic viscosity at 100°C.
Whats SAE oil mean?
the Society of Automotive Engineers
A letter for every lubricant type Therefore the first three letters you need to know are SAE, the acronym of the Society of Automotive Engineers. This society is responsible for establishing a classification system based solely on oil viscosity.
