What is 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.

How can you tell the quality of grease?

Best Methods for Analyzing Grease

  1. Atomic Emission Spectroscopy.
  2. Particle Quantifier Index.
  3. Fourier Transform Infrared Spectroscopy.
  4. Karl Fischer Titration.
  5. Bleeding Test.
  6. Penetration Test.
  7. Sulfate Ash.
  8. Shear Stress, Visible Viscosity.

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.

What is specification of grease?

Proper grease specification requires all of the components of oil selection and more. Other special considerations for grease selection include thickener type and concentration, consistency, dropping point and operating temperature range, worked stability, oxidation stability, wear resistance, etc.

What’s the difference between ep1 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 grease analysis?

Condition-based grease analysis can identify changes in grease consistency, viscosity and oxidation stability and help in determining its remaining useful life. Contamination, base oil depletion and a variety of mechanical issues can affect grease’s ability to remain in contact with and protect metal surfaces.

How is grease viscosity measured?

Grease Viscosity (Consistency) They usually are used in applications where a liquid lubricant would run out. Greases are sold by consistency grade, which in this case will be used synonymously with viscosity grade. Grease consistency is measured using the cone penetration test.

Is grease a Newtonian?

Since a grease is non-Newtonian, we can only measure the apparent viscosity because the viscosity of a non-Newtonian fluid changes with shear stress (see “Understanding Absolute and Kinematic Viscosity” by Drew Troyer). The apparent viscosity of a grease is determined using ASTM D1092.

What viscosity is grease?

Grease is usually lithium, with a normal viscosity of 100 centistokes. This typically has a maximum operating temperature of 121 C (250 F), but it is usually limited to a service temperature of 93 C (200 F).

What do numbers mean on grease?

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 is the difference between EP 1 and EP 2 grease?

How is the thickness of grease measured?

The simplest method of determining tackiness is a finger test. A blob of grease is squeezed between the finger and thumb and then this finger and thumb are pulled apart. A similar test using a spatula is shown in Fig. 2.

What is NLGI number of grease?

The NLGI number is a measure of the grease’s consistency as indicated by its worked penetration value. The penetration test measures how deep a standard cone falls into a grease sample in the tenths of millimeters. Each NLGI grade corresponds to a specific worked penetration value range.

What is EP1 and ep2 grease?

Product Description. Mobilux EP 0, 1, and 2 products are a high performance family of five general-purpose industrial greases and two special-duty semi-fluid greases. These lithium hydroxystearate greases are formulated to provide extra protection against wear, rusting and water washout.
