Abstract
Official abstract text for this publication.
There is provided a rolling bearing which inhibits spalling of a rolling element and has a long service life even under rigorous environments. The rolling bearing comprises grease for lubricating rolling contact parts and/or sliding contact parts between a first raceway surface and a rolling elements and/or between a second raceway surface and a rolling elements, wherein the grease comprises a base oil, a thickener and an extreme pressure additive, the thickener is a diurea compound obtained by allowing an amine mixture comprising alkylphenylamine, alkyl group of which has 8 to 16 carbon atoms, and cyclohexylamine, to react with a diisocyanate compound, an amount of cyclohexylamine in the total amount of the alkylphenylamine and cyclohexylamine is from 91 to 99% by mole, and a reaction temperature of the extreme pressure additive with iron is 260° C. or lower.
First claim
