A fan device with oil-retaining bearing includes a base seat and an oil-retaining bearing. The base seat has a central tubular section and a bearing cup extending from the central tubular section to one side. The bearing cup has an internal bearing hole. The central tubular section has at least one mating section in adjacency to the bearing hole. The oil-retaining bearing is disposed in the bearing hole. The oil-retaining bearing has at least one connection section mated with the mating section. The connection section and the mating section are mated with each other so that the oil-retaining bearing is securely disposed in the bearing hole. In addition, the operation of the shaft will not be affected due to the press fit and the difficulty in controlling the glue dispensing process.

The pulley part has an inner portion with a frustoconical inner surface mounted on an outer cylindrical surface of the outer ring, an outer cylindrical portion having an outer cylindrical surface configured to support a belt or a chain, and an intermediate portion extending radially inward from the cylindrical outer portion to the inner portion. The pulley part is integral and has an open end on an axial side opposite the intermediate portion. The frustoconical surface extends inwardly towards the outer ring, and the inner surface is force fitted onto the outer cylindrical surface of the outer ring.

A combined electrical insulator and conductor assembly for a bearing disposable between a shaft and a housing. An annular insulator is disposeable about the bearing and configured to prevent electric current flow between an outer ring and the housing. An electrical conductor has retainer(s) releasably engaged with the insulator so as to couple the conductor with the bearing, an outer radial end and an inner radial end. The conductor outer radial end, or/and a portion of the conductor between the outer and inner ends, is conductively engageable with the housing and the conductor inner radial end is conductively engageable with the shaft so as to provide an electrically conductive path between the shaft and the housing. Preferably, the conductor includes a conductive disk having arcuate retainer clips engageable with an insulator groove of the insulator and a brush subassembly including conductive fibers engaged with the shaft outer surface.

A bearing structure includes a bearing that supports a propeller shaft, an annular vibration isolating member fitted over the bearing, an outer ring attached to the vibration isolating member and having an outer-peripheral fitting surface, and a bracket attached to a vehicle body and having an inner-peripheral fitting surface that is fitted to the outer-peripheral fitting surface.
