What type of grease is used to lubricate?

What type of grease is used to lubricate?

Lithium-based greases are the most commonly used; sodium and lithium-based greases have higher melting point (dropping point) than calcium-based greases but are not resistant to the action of water.

What are the five rules for good grease lubrication?

The Five Rights of Lubrication

• Right type. As a first step in the lubrication of equipment, refer to the OEM manual, and contact the OEM if you have any questions.
• Right quality.
• Right amount Grease lubrication…
• Oil lubrication…
• Right place.
• Right time.
• Oil…
• Conclusion.

How many types of lubricant grease are there?

There are mainly three different types of lubrication commonly available in the market: boundary, mixed and full film.

What do grease colors mean?

Dark blue – typically for multipurpose greases made from conventional oil base stocks. Red – mostly for multipurpose synthetic greases. Grey – for those containing moly for many off-road equipment specifications, and. White or undyed greases – typically used in paper machines or food-grade applications.

What is the most important grease specification?

The most important property of any lubricant is viscosity. A common mistake when selecting a grease is to confuse the grease consistency with the base oil viscosity. Because the majority of grease-lubricated applications are element bearings, one should consider viscosity selection for those applications.

What are the grades of grease?

Grease Properties Greases are classified into nine consistency grades (000, 00, 0, 1, 2, 3, 4, 5, 6) established by the National Lubrication and Grease Institute (NLGI). NLGI #000 greases are nearly fluid, while NLGI #6 greases are nearly solid. The most commonly used grease is NLGI #2.

Does the Colour of grease matter?

While operators tend to associate the grease they use with a color, like deep red or bright blue. As described in the video from Mobil below, the color of the grease does not change the performance characteristics and it is only the manufacturer who determines what color their grease is.

Which Colour grease is best?

The Effect of Color on Lubricating Grease Although there is no hard and fast rule, red could be indicative of grease for high temperatures, blue for cold temperatures and green for environment friendliness. Below are some interesting results regarding the effects of color on grease properties.

What do grease numbers mean?

The NLGI consistency number (sometimes called “NLGI grade”) expresses a measure of the relative hardness of a grease used for lubrication. The higher the NLGI number, the firmer/thicker the grease. The NLGI consistency number alone is not sufficient for specifying the grease required by a particular application.

What are the 7 purposes of lubrication?

To lubricate each part of the bearing, and to reduce friction and wear. To carry away heat generated inside bearing due to friction and other causes. To cover rolling contact surface with the proper oil film in order to prolong bearing fatigue life. To prevent corrosion and contamination by dirt.

What’s the difference between number 1 and number 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 is black grease used for?

#6588 Black Grease Example uses: CVA joints, metal ring and pinion gear surfaces, differential thrust bearings, inside ball cups to ease installation onto turnbuckles, and on screws threading into hard plastic.

What are the types of lubrication?

There are three different types of lubrication: boundary, mixed and full film. Each type is different, but they all rely on a lubricant and the additives within the oils to protect against wear. Full-film lubrication can be broken down into two forms: hydrodynamic and elastohydrodynamic.

What does 00 mean in grease?

This institute developed the NLGI Consistency Grade Scale, which assigns numerical ratings in relation to the hardness of the grease. The scale ranks as follows: 000 is very fluid, 00 is semi-fluid, 0 is fluid, 1 is soft, 2 is medium, 3 is medium-hard, 4 is hard, 5 is very hard, and 6 is block.
