The invention relates to a part vibration reducing material of a rail wagon, in particular to an elastic side bearing body material for a bogie of the rail wagon, which is used for manufacturing the elastic side bearing body for the bogie. The elastic side bearing body material comprises the following components by weight part: 80-110 parts of natural rubber, 10-30 parts of butadiene rubber, 3-8 parts of zinc oxide, 0.5-1.5 parts of stearic acid, 0.2-2.0 parts of aging resisters 4010NA, 0.2-2.0 parts of aging resisters D, 0.2-2.0 parts of microcrystalline wax, 0.2-2.0 parts of dispersing agents D-4A, 0.5-1.5 parts of accelerating agents CZ, 1.0-3.0 parts of sulfur, 0.5-1.2 parts of accelerating agents TMTD, 10-40 parts of intermediate super-abrasion furnace carbon blacks, 5-20 parts of fast extruding furnace carbon blacks and 0-10 parts of low-temperature plasticizers. The JC type elastic side bearing body of the rail wagon, which is made from the elastic side bearing body material in the invention, has the a
