Hello everyone!

Is mixing oil and grease a good practice for open gear lubrication? What NLGI number do you usually use for open gear lubrication?

Any suggestions and comments would be deeply appreciated

Grease out of girth gear + drained oil (both used) mixed - offer good lubrication for open gear lubrication. Try to get a magnetic seperator to eliminate Fe particals

Not a good idea to mix oil and grease.
Properties needed for open gear lubs are good adhesion and EP properties, oil viscosity and pumpability.
Own blending will probably upset these properties.
Products available from NLGI 000 to stiffer grades.
Some very good products in the market place usually containing solid lubricants.

The answer is a definite No for mixing grease and oil for open gear lubrication. These gears are usually very expensive pieces of machinery and to guess at the mixture required to lubricate them is false economy. Look below in this forum at the "Sprayable Open Gear Lubricants" thread for more information on OGL's.

I wouldn't recommend "making your own" grease. It would be better to get a grease with the correct viscosity from the start that has been properly formulated for the task at hand. If your looking for some "splash effect" then NGLI #2 is probably to thick unless it's in a very hot environment. It sounds like your looking for a semi-fluid grease, something in the NGLI #0 or #00 range. The NGLI #00 is similar to a very thick gear oil. Put some in a cup and tip it on it's side and it will begin to run out of the cup.

My suggestions would be either Millennium 2200 or Takilube, both which come in NGLI #0 and #00 (the more 0's the thinner the grease). I'm not sure how your applying the grease but the Takilube is available in caulking tubes as well as regular pail and drum containers. The caulking tubes make hand application very easy. I would also recommend the Takilube in very dirty environments as that is what it is designed for, that being exposed gears, dipper stick and rack's as well as chains and cables.

In any case I wouldn't suggest formulating your own by mixing grease and gear oil, the properties of the resulting blend will be unknown to you until it is to late.

It is not a great idea to make your own combination of Oil and grease for a heavy loaded application like open gear.

There are a number of good manufacturers for Open Gear Lubricants. For Cement Plants Opne gears -Girth applications - Fuchs/Becham are well known. Omega is well known in Sugar Mill type Gears.

Rather than mixing oil and grease at ones own place ,better ask better consult a lubricant manufacturer and get the grease of right consistency that is NLGI 0 or NLGI 00,having EP properties.

Hello
It is a not good idea. The serious unequal mixture(mixing) in a closed system, putting in risk the mechanism. In the stops of the mechanism made separation of fat and oil. For opened mechanisms better fats NLGI 2 or NLGI 3 with based oil high viscosity. But in system gear´s closed opereted slow revolution and big charges better greases EP-DEPENDING VELOCITY OF THE SYSTEM- NLGI 0, 00, 000.
