What is Chevron SRI Grease?
Chevron SRI grease is a high-temperature, NLGI 2 grade, ball and roller bearing grease designed for a wide range of applications. It is recommended for anti-friction bearings operating at high speeds in high temperatures, or where there is a likelihood of corrosion.
What is Sri 2 grease?
SRI Grease 2 is a high performance high temperature ball and roller bearing grease. It is dark green in colour and has a smooth, buttery structure. SRI Grease 2 is formulated with highly refined base stocks, a high performance ashless organic polyurea thickener and robust anti-rust and anti-oxidation additives.
What color is Chevron SRI Grease?
dark green
Its texture is smooth and buttery and its color is dark green. As noted, Chevron SRI Grease 2 passes the Static Bearing Rust Test, ASTM D5969, with 10% synthetic sea water. These properties help to provide longer bearing life under high speed and high temperature operation.
Is synthetic grease compatible with lithium grease?
Lithium and polyurea greases cannot be mixed. “They can cause each one to lose their oil and dry out,” said Hamilton. The product loses the ability to lubricate.
Is ep2 grease the same as NLGI 2?
We are all familiar with “EP 2” grease. This tells us two things, EP 2 grease is a NLGI Grade 2 and it is fortified with Extreme Pressure (EP) additives. This tells us nothing else about the thickener type, base oil type or viscosity of the base oil.
Are lithium and polyurea grease compatibility?
Greases based on simple lithium soaps (lithium stearate or lithium 12-hydroxy stearate) and lithium complex soaps may or may not be compatible with polyurea greases. The reason being, some polyurea thickeners are completely compatible with lithium and lithium complex thickeners, while others are incompatible.
Can you use cv grease on wheel bearings?
If the Grease is Good for CVs, it can’t be used on Bearings. Likewise, if the Grease is good for Bearings, it can’t be used on CVs. Proper CV Grease is very tacky and may (usually) not allow the rolling elements of a bearing to roll, but usually slide.
Is it OK to mix synthetic grease with regular grease?
Don’t Mix Grease, but Change If Needed If you can, start with completely clean parts and new grease. Otherwise, greasing more often will flush out the old incompatible grease faster.
What types of greases are not compatible?
Greases based on simple lithium soaps (lithium stearate or lithium 12-hydroxystearate) and lithium complex soaps (containing simple soap and a complexing agent, such as lithium azelate) may or may not be compatible with polyurea greases.
What does NLGI #2 mean?
NLGI Grades 1-3 The most commonly used greases, such as those used in automotive bearings, would use a lubricant that is NLGI grade 2, which has the stiffness of peanut butter. Grades within this range can operate in a higher temperature range and at higher speeds than NLGI grades 000-0.
Is lithium grease NLGI 2?
Multipurpose Grease: Lithium, White, 14 oz, NLGI Grade 2, NSF Rating H2 No Food Contact. Country of Origin USA. Country of Origin is subject to change.
Which is better polyurea or lithium grease?
On average, polyurea greases can have a three to five times better life expectancy than lithium-based greases. On the other hand, lithium complex is the most common thickener on the market, making up nearly 60 percent of the greases available in North America.
