The invention discloses a novel floating bearing for a turbocharger. The floating bearing comprises a floating bearing body, wherein an annular oil groove is formed in the outer working surface of the floating bearing body; a plurality of lubricating oil holes penetrating through the wall of the floating bearing body are circumferentially formed in the annular oil groove at intervals; a plurality of outer working surface oil wedge surfaces are circumferentially arranged on the outer working surface of the floating bearing body; a plurality of inner working surface oil wedge surfaces are circumferentially arranged on the inner working surface of the floating bearing body. The floating bearing has the beneficial effects that hydrodynamic effects of fluid are achieved by the oil wedge surfaces, so that the film bearing capability of the floating bearing of the turbocharger can be remarkably improved, the swinging of a rotor shaft can be reduced, two support surfaces can be effectively isolated, the frictional wear of the floating bearing can be reduced, the transient response characteristic and reliability of the turbocharger can be improved, and the service life of the turbocharger can be prolonged; in addition, the phenomenon of abnormal abrasion of the floating bearing due to insufficient oil pressure can also be effectively avoided, the floating bearing can be adapted to a severer working environment, and the lubrication and frictional wear characteristics of a friction pair are remarkably enhanced.
