What do the 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 EP gear oil?
ADVANTAGE EP GEAR OILS are premium quality industrial gear lubricants made from highly refined base stocks and modern additive technology. These lubricants are designed to provide excellent performance when load carrying capacity is required due to extreme pressures and shock loading.
What is SAE 90 hypoid gear oil?
Monograde hypoid transmission oil for synchronized and not synchronized manual transmissions and for axle transmissions, transfer cases, intermediate gear boxes, ancillary transmissions in vehicles and work machines.
Is 80w90 the same as 90W?
80W-90 oil is as thin as an 80W oil when cold, and as thick as a 90W oil when hot. A 90W oil is 90W hot or cold. So an 80W-90 will be a little bit thinner than a 90W when cold, but will be essentially the same when hot.
What is the viscosity of 90 weight gear oil?
To compare viscosities across the chart, R&D lab technicians follow a process called “read-across.” By reading across the chart, we see that at operating temperature, a viscosity of 18 cSt can describe 50-weight crankcase oil and 90-weight gear oil.
Is 80W-90 the same as 10W 40?
The most common mistake is the belief that the viscosity of SAE 80W gear oil is much thicker than the viscosity of SAE 10W-40 motor oil. This is absolutely incorrect!
What does EP 90 mean?
Classic Gear EP 90 is a mineral SAE 90 transmission oil. The product is suitable for use in manual transmissions and other transmissions in classic vehicles that require a medium single-grade oil with extreme pressure protection that meets the API GL-4 specification.
What does EP mean in lubricant?
extreme pressure
January 26, 2017 – What does EP mean in the name of a lubricating grease? The term EP refers to extreme pressure, which means the grease is formulated with additives that increase its load carrying capacity.
What is the difference between hypoid gear oil and regular gear oil?
What is the difference between hypoid and regular gear oil? It’s a gearbox oil, just like others, but the ingredients are different. This type of gear oil is mixed with additives designed to increase its resistance to breakdown under high temperature and mechanical pressure produced by hypoid gearboxes.
What does hypoid mean in oil?
A hypoid gear oil is a lubricant that is designed to operate effectively with hypoid gear designs. Most gearboxes and differentials use hypoid gear designs and the lubricant must contain EP (extreme pressure) additives to prevent wear between the sliding surfaces of a hypoid gear mesh.
