ABSTRACT:
The use of bismuth-compounds in an extreme pressure grease lubricant composition for rolling bearing applications can extend the useful service life of rolling bearings. The bismuth can be used as an additive, preferably an EP additive, or as a soap or non-soap thickener. The invention further relates to a method for preparing an extreme pressure lubricant composition in which a bismuth containing soap or thickener is mixed with an oil and optionally one or more EP- or other additives.
