A reciprocating hermetic compressor includes a cylinder block internal to a shell and carrying a cylinder and a radial bearing hub; a crankshaft vertically mounted in the radial bearing hub and carrying, inferiorly, a rotor of an electric motor and, superiorly, a support annular face and an eccentric portion. The radial bearing hub incorporates an upper tubular extension, bearing a corresponding extension of the crankshaft and around which is mounted an axial rolling bearing for supporting the weight of the crankshaft-rotor assembly, as well as the axial stresses produced during compression of the refrigerant gas.
