  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.

  本发明的一个目的是提供一种润滑脂组合物，即使其中混有水，也能长时间保持良好的润滑状态，从而抑制白色结构剥落和腐蚀。另一个目的是提供一种车辆轮毂单元轴承，即使在可能渗水的环境中使用，该轴承也几乎不会出现白色结构剥落和腐蚀，因此具有较长的使用寿命。 本发明提供了一种滚动轴承，其中密封有一种含防水成膜添加剂的润滑脂组合物；一种用于轮毂单元轴承的润滑脂组合物，其中含有一种基础油，其主要成分至少包括矿物油和合成油中的一种，以及一种稠化剂和一种剥落抑制剂；以及一种密封有该润滑脂组合物的车辆轮毂单元轴承。
