The invention provides a preparation method of a sliding bearing and a track roller, preparation raw materials of the sliding bearing comprise a matrix phase, a filling phase, a reinforcing phase, a wear-resistant phase and a heat conduction phase, the matrix phase is engineering plastic or special engineering plastic, the manufacturing cost is low, and the sliding bearing has good bearing capacity and cold and hot deformation capacity; the sliding bearing has the advantages that the probability of falling caused by deformation of the sliding bearing due to the temperature effect is reduced, good wear resistance is achieved, long-time effective operation can be achieved under the oil-free working condition, and the preparation method comprises the following steps that S1, the preparation raw materials are mixed in a high-speed mixing machine; s2, putting the uniformly mixed preparation raw materials into a twin-screw extruder for extrusion granulation to obtain plastic particles; s3, the plastic particles are dried in a drying oven; and S4, the completely dried plastic particles are subjected to injection molding, and the sliding bearing is obtained. S5, the sliding bearing is put into a drying oven to be subjected to annealing treatment; an annealing process is added to eliminate internal stress of the sliding bearing and improve deformation resistance of the sliding bearing.
