CENTRAL GREASING GREASE COMPOSITION FOR HIGH-SPEED BEARING

摘要

PURPOSE:To obtain the subject composition having excellent force-feeding property, shearing stability and oil-separation property and prolonged service life by using a mineral oil as the base oil and compounding a specific aromatic diurea compound CONSTITUTION:This grease composition contains (A) a mineral oil as the base oil and (B) 12-1wt.% of an aromatic diurea compound of the formula (R1 and R3 are a 6-12C aromatic hydrocarbon residue; R2 is a 6-15C aromatic hydrocarbon residue) as a thickening agent. The apparent viscosity of the composition at 0 deg.C is <=900Pa.s {9000P} at a shearing rate of 1s<-1> and <=180Pa.s {1800P} at a shearing rate of 10s<-1>.
