What is the difference between #1 and #2 grease?
Less thickener makes a #1 grease more tractable and slippery, while #2 grease has more thickener, making it stiffer and great for all-purpose applications. Despite what is commonly believed, grease application during the winter is not a “one and done” situation.
What are the three 3 main components of a grease?
Greases are manufactured by combining three essential components: base oil, thickener, and additives.
Is grease a liquid or solid?
solid
Very simply: Greases are usually oils with thickener added. At room temperature, greases are usually solid, while oils are usually liquid. All oils can be turned into greases, but not all greases come from oils.
What is the difference between NLGI 2 and 3?
A grease with an NLGI grade of 1 has a consistency like tomato paste, where a grease with an NLGI grade of 3 has a consistency more like butter. 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.
How many types of grease are there?
All these seven types of grease can be referred to as multipurpose (MP) greases, extreme pressure (EP) greases, marine greases, heavy-duty greases, specialty greases, automotive greases, industry greases, and so on, depending on the unique properties of base oils, additives, and thickeners used in the process of …
What does NLGI stand for in grease?
National Lubricating Grease Institute
Traditionally, a grease’s stiffness is indicated by its penetration value and is evaluated using the standardized National Lubricating Grease Institute (NLGI) grade chart. The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value.
Is grease a lipid?
What is grease? Grease is the common term for animal fats and vegetable oils. Animal fats and vegetable oils are lipids. Lipids are organic molecules essential to animal life for the production of hormones and energy storage.
What is the difference between EP 1 and ep2 grease?
Mobilux EP 0 and 1 are suitable for centralised systems. Mobilux EP 2 are general-purpose greases. The recommended operating temperature range is from -20ºC to 130ºC, but they may be used at higher temperatures if the lubrication frequency is increased accordingly.
What is EP 2 grease used for?
EP-2 grease is recommended for lubrication of U-joints, tripod CV joints, drive shafts, release bearings in clutches and brakes with high temperature conditions. It is also suitable for machinery in construction, dredging, forestry, marine, and mining where this type of grease is required.

What is fats oils and grease?
Fats, oils, and grease (FOG) comes from meat fats in food scraps, cooking oil, shortening, lard, butter and margarine, gravy, and food products such as mayonnaise, salad dressings, and sour cream. FOG poured down kitchen drains accumulates inside sewer pipes.
What is the specification of grease?
The softer the grease, the lower the number. Grease for bearings are typically NLGI 1, 2 or 3….Consistency.
| NLGI number | ASTM worked penetration (10–1 mm) | Appearance at room temperature |
|---|---|---|
| 0 | 355–385 | semi-fluid |
| 1 | 310–340 | very soft |
| 2 | 265–295 | soft |
| 3 | 220–250 | medium hard |
What is the classification of Grease for bearings?
It is classified according to a scale developed by the NLGI (National Lubricating Grease Institute). The softer the grease, the lower the number. Grease for bearings are typically NLGI 1, 2 or 3. The test measures how deep a cone falls into a grease sample in tenths of mm. Comprehends the suitable working range of the grease.
What is an example of a common grease?
Common greases are in the range 1 through 3. Those with a NLGI No. of 000 to 1 are used in low viscosity applications. Examples include enclosed gear drives operating at low speeds and open gearing. Grades 0, 1 and 2 are used in highly loaded gearing.
What is a Grade 1 grease used for?
Common greases are in the range 1 through 3. Those with a NLGI No. of 000 to 1 are used in low viscosity applications. Examples include enclosed gear drives operating at low speeds and open gearing. Grades 0, 1 and 2 are used in highly loaded gearing. Grades 1 through 4 are often used in rolling contact bearings.
How are grease codes assigned to grease?
It assigns a single multi-part code to each grease based on its operational properties (including temperature range, effects of water, load, etc.) and its NLGI consistency number. Silicone grease is based on a silicone oil, usually thickened with amorphous fumed silica .
