    Abstract: A bearing for a motorized fuel pump is made of a Cu—Ni based sintered alloy, composed of: 21 to 35% by mass of Ni, 5 to 12% by mass of Sn, 3 to 7% by mass of C, 0.1 to 0.8% by mass of P, and the balance of Cu and inevitable impurities. A matrix of the bearing is formed with pores with a porosity of 8 to 18%, and the P component is predominantly included at the grain boundary, and free graphite is distributed along the insides of open pores that are open to the surface and extending into the bearing. In this bearing, a Sn rich alloy layer containing equal to or more than 50% by mass of Sn is formed on the insides of the open pores and near openings of the open pores.

    Abstract: A sintered fluid dynamic pressure bearing completely seals or decreases the sizes of gaps formed in pores by shrinkage when a resin impregnated therein shrinks. The fluid dynamic pressure bearings can be reliably and easily produced using fewer processes while superior quality is maintained. A production method for a fluid dynamic pressure bearing includes a resin sealing process including a resin impregnating step in which a monomer of an anaerobic resin composed primarily of acrylate or methacrylate is impregnated in pores of a porous sintered compact, an excess resin washing off step in which excess resin adhering to the surface of the porous sintered compact is washed off, and a resin curing step in which the monomer of the anaerobic resin impregnated in the pores is cured by heating the porous sintered compact to at least the curing temperature of the resin after washing off the excess resin; the resin sealing process is repeatedly carried out, and a monomer of an anaerobic resin containing an organic peroxide at 0.1 to 1.0 mass % is used in at least the resin impregnating step of the last resin sealing process.
