Claims23
A bearing assembly comprising:
- a bearing inner ring having an inner raceway on an outer surface thereof;
- a bearing outer ring having an outer raceway on an inner surface thereof, said outer ring positioned such that the inner raceway is in an opposed and spaced apart relation from the outer raceway;
- a plurality of rolling elements disposed between the inner raceway and the outer raceway;
- a lubricant disposed about the rolling elements between the inner raceway and the outer raceway;
- said lubricant comprising a hydrocracked base oil and a lithium complex thickener.
A rolling element bearing grease comprising a hydrocracked base oil and a lithium complex thickener, wherein the lithium complex thickener comprises 15-18% of the grease.
A rolling element bearing grease comprising a hydrocracked base oil and a lithium complex thickener, further including EP additives comprising 3-5% of the grease.
A rolling element bearing grease comprising a hydrocracked base oil and a lithium complex thickener, further including a corrosion inhibitor comprising 3-5% of the grease.
A rolling element bearing grease comprising a hydrocracked base oil and a lithium complex thickene, wherein the lithium complex thickener comprises 15-18% of the grease, said grease further including EP additives comprising 3-5% of the grease and a corrosion inhibitor comprising 3-5% of the grease.
