The invention relates to a bearing outer ring for automobiles, solving the technical problem that the prior art is not reasonable enough in design. The bearing outer ring comprises a ring body, a first cylindrical through hole, ring-shaped convex rings, a first roller path, a second roller path, first tapered ring bodies, second tapered ring bodies, a first stop part, a second stop part, first ring-shaped abdicating grooves, a second cylindrical through hole, a third tapered ring body, second ring-shaped abdicating grooves, a third cylindrical through hole and a fourth tapered ring body, wherein oil storage grooves are formed in the first and second roller paths and are respectively connected with oil inlet channels; the oil inlet channels are respectively communicated with oil inlets; the ring body comprises a first barrel-shaped body, a tapered barrel and a second barrel-shaped body; an installation ring body is arranged at the end of the second barrel-shaped body via first arc-shaped transition parts; a necking barrel is connected at the end of the installation ring body; the second cylindrical through hole is formed in the necking barrel. The bearing outer ring for automobiles has the advantages that the bearing outer ring for automobiles has high precision, enables steel balls to roll smoothly when in use and has high strength.
