The invention relates to a dual wearing plate elastic side bearing, which comprises a high side bearing and a low side bearing that are parallelly mounted on a bogie of a railway vehicle, wherein the high side bearing comprises a high side bearing body and a high side bearing wearing plate mounted on the top portion of the high side bearing body; the low side bearing comprises a low side bearing body and a low side bearing wearing plate mounted on the top portion of the low side bearing body; and the friction coefficient of the high side bearing wearing plate is larger than that of the low side bearing wearing plate. The dual wearing plate elastic side bearing can be widely applied to the bogie of the railway vehicle in which a full side bearing load-carrying method is adopted. According to the invention, the wearing plates are respectively used to provide steering resistance torque for the high side bearing and the low side bearing; the friction coefficient is more stable; the problems such as the rising of rollers are avoided to happen; the mounting port sizes of the wearing plates of the two side bearing plates are adopted with different values, so that the high side bearing wearing plate and the low side bearing wearing plate can't be exchanged when being mounted; the purpose of wrongly mounting is avoided; and the mounting is simple and convenient.
