Zusammenfassung:	Composition of bearing lubricating greases comprises: (a) a silicone oil having a viscosity of 100-1000 cSt at 25 deg C as the base oil component; (b) a diurea compound as thickener having a mixing ratio of 2-30 wt.% and a formula: R1NHC)NHR2NHCONHR3, (where R2 = aromatic divalent 6-15C hydroxyl; and R1 and R3 = saturated 6-18C alkyl and cyclohexyl). The ratio of saturated alkyl to cyclohexyl is 5-95 to 95-5 mol.%.
