1. SCOPE This specification covers a lithium soap and silicon oil grease to be used for lubrication of accelerator bearing control, shielded roller bearing ball and other parts in a range of -73 degrees C to 180 degrees C.

Material Description. This specification defines grease formulated with synthetic hydrocarbon oil and calcium sulfonate thickener with a National Lubricating Grease Institute (NLGI) rating of 2. Symbols. Not applicable. Typical Applications. This grease is...

Material Description. This specification defines grease composed of perfluoropolyether oil and polytetrafluoroethylene or Polyurea thickener. Symbols. Not applicable. Applicability. Grease defined by this specification is intended for applications requiring resistance to...

The primary challenges facing grease lubrication research today are three-fold. The first challenge is to develop greases that will provide longer life and/or are able to operate under more severe conditions (extreme low and high temperature and speed). The second...

Material Description. This specification defines grease composed of silicone oil and inorganic thickening agents (amorphous silica, lithium soap, or polytetrafluoroethylene). Symbols. Not applicable. Applicability. Grease defined by this specification may be used on...

This specification specifies the general requirements of grease used for lubrication of the gear, plain bearing and axle spline shaft.

Scope. This specification covers one grade of grease for multipurpose usage in applications requiring water resistance. It is to be used at temperatures ranging from -18 to 110 °C (0 to 230 °F) in all shipboard applications requiring dispensing through long lengths of tubing. The temperature...

Material Description. A grease having high temperature, extreme pressure, and other characteristics suitable for lubrication of tapered roller wheel bearings. Symbols. Not applicable. Applicability. This grease is typically used for lubrication of tapered roller wheel bearings...

This method is used for determining the tendency of the oil in lubricating grease to separate at elevated temperature. It consists of heating the specimen in a wiregauze cone under static conditions for the time and at the temperature required by the specification, then...

This Commercial Item Description (CID) covers the performance requirements of a synthetic base hydrocarbon grease thickened with a lithium complex soap that is intended for application as a lubricant for sealed bearings used in electric motors on Navy ships and submarines. It is not...

Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose/Material Description. Greases approved to this specification with be...

Material Description. This specification defines mineral oil grease with bentonite thickener. Symbols. Not applicable. Applicability. This grease is designed primarily for automotive brake calipers. Remarks. This specification describes requirements for grease used by...

Material Description. Grease shall be a smooth homogeneous mixture of petroleum oil and a polyurea thickener. Additives to improve oxidation stability, rust inhibition, mechanical stability, and wear resistance may be included. Symbols. Not applicable. Applicability....

This method consists of removing a Timken bearing cup at a given rate from a grease cup and measuring the length of string.

SCOPE THIS SPECIFICATION COVERS A LUBRIFICANT GREASE COMPOSED BY POLYALPHAOLEFIN AND MINERAL OIL, SODIUM COMPLEX BASIS. THE GREASE SHALL BE USED AS LUBRIFICANT IN CLUTCH PARTS.

1.1 This test method covers a laboratory procedure for evaluating the high-temperature life performance of wheel bearing greases when tested under prescribed conditions. Note 1: Changes to this test method in the 1985 revision increased test severity. Results will not be comparable...
