摘要： The present invention provides water-resistant grease which improves the resistance to peeling which occurs from the surface of a bearing composed of carbon steel for machine structural use or the like even in a strict lubricating condition in which water may penetrate into the water-resistant grease during the operation of the bearing, and a rolling bearing and a hub bearing which use the water-resistant grease and have a long life. The water-resistant grease is composed of non-water-based base oil, a thickener, and a water dispersant used as an additive. The saturated amount of water dispersible in the water-resistant grease is 30 to 60 wt %. The water dispersant capable of dispersing the water in the water-resistant grease is a surface active agent. The non-water-based base oil is mineral oil. The thickener is a urea-based compound. The present invention also provides a rolling bearing and a hub bearing in which the water-resistant grease is enclosed.

摘要： A fluid dynamic bearing apparatus with an increased adhesive strength between a component having an adhesion fixing face and a bracket is provided by appropriately controlling the adhesion gap. Materials for a bracket and a housing are selected so that the value obtained by dividing the linear expansion coefficient of the housing fixed to the inner periphery of the bracket by the linear expansion coefficient of the bracket having a portion for mounting a stator coil of a motor is not lower than 0.5 but not higher than 2.0. An adhesion fixing face formed on the outer periphery of the housing is adhesively fixed to the inner circumferential surface of the bracket with an anaerobic adhesive or an epoxy-based adhesive.
