Publication number: 20090003742Abstract: An object of the invention is to provide a grease composition capable of keeping a good lubrication condition for a long period of time even when water has mixed therein, thereby inhibiting white structure flaking and corrosion. Another object is to provide a vehicular hub unit bearing which hardly suffers from white structure flaking and corrosion even when used in an environment where water may penetrate into it and which therefore has a long life. The invention provides a rolling bearing with, sealed up therein, a grease composition containing a waterproof film-forming additive added thereto; a grease composition for hub unit bearings, containing a base oil that comprises at least one of mineral oil and synthetic oil as the main ingredient thereof, and a thickener and a flaking inhibitor; and a vehicular hub unit bearing with the grease composition sealed up therein.Type: ApplicationFiled: January 24, 2006Publication date: January 1, 2009Applicants: NSK LTD., KYODO YUSHI CO., LTD.Inventors: Shinya Nakatani, Jun Kuraishi, Tomoaki Matsumoto, Minoru Namiki, Ryo Aida, Toshiaki Endo
