the Expert Q:
Can you confirm that there are no greases with a NLGI consistency number with a “Grade N2” designation?
A:
We can confirm that there is no NLGI consistency grade designated N2. Please visit the NLGI website for a complete listing of all NLGI Certified greases with the consistency grade included.
Q:
We are trying to qualify a grease for an NLGI classification - what needs to happen get this done? We will be performing D217 Cone Penetration on their grease - would you accept our results to qualify the grease?
A:
The requirements for qualifying a grease against the NLGI GC or LB service categories are detailed in ASTM D4950. All tests listed must be performed to qualify a grease against either of the categories. A D217 Penetration test performed as prescribed in the test method is considered to be suitable to be part of the data used to qualify the grease.
Q:
My company has a standard grease we¹re currently using. But it is causing us some problems so we are looking at alternatives. I am trying to find a list of grease manufacturers that have a significant international presence. If I find the perfect grease in USA and it isn¹t available in China, Brazil, etc. it does me no good. Is that something your organization can help with?
A:
NLGI cannot recommend a grease manufacturer, as there are many that make up NLGI’s membership. However, there are many grease manufacturers with an Internet presence or that can be found in trade magazines, journals, and periodicals. Most multinational oil companies produce lubricants and greases and most of them have presence in major industrial markets such as the USA, Europe, Japan, China, Brazil, etc. Attending NLGI’s annual meeting is an opportunity to network with many grease manufactures.
