The utility model discloses a long-service-life universal joint bearing which mainly comprises a shaft sleeve, a roller pin and a gasket, the shaft sleeve is used for being sleeved on a shaft neck ofa cross shaft, the roller pin is installed between the shaft sleeve and the shaft neck, one end of the roller pin abuts against a roller pin check ring installed on the shaft neck, and the other end of the roller pin abuts against the gasket. The surface of the shaft sleeve inner ring is of a wave-shaped structure, and a wave-shaped curve is a sine wave, so that the shaft sleeve inner ring is in flexible surface contact with the surface of the roller pin. According to the utility model, the overall dimension of the shaft sleeve is not changed and the motion performance of the bearing is not influenced; a wavy shaft sleeve design is adopted; the contact area between the roller pins and the shaft sleeve inner ring is effectively increased; and by improving the height size of the gasket, changing the matching position of the roller pin and the outer ring, avoiding a stress concentration point and reducing the contact stress, the contact stress of the roller pin and the inner ring of the shaft sleeve is reduced by more than 15%, the fatigue life of the bearing is prolonged by more than 10%, and the service life of the universal joint bearing is effectively prolonged.
