The invention discloses a gapless wheel set radial device and a bogie. The gapless wheel set radial device comprises a radial arm, a cross rod, a connecting pin, an upper plane bearing, a lower plane bearing, an elastic block and a fastener. The radial arm comprises a top plate and a bottom plate, a mounting groove of the cross rod is formed between the top plate and the bottom plate in the vertical direction, and a first taper hole is formed in the top plate; a second taper hole is formed in the bottom plate; the axis of the first taper hole and the axis of the second taper hole are coaxial up and down, and the first taper hole and the second taper hole are both in an inverted cone shape. An outer conical expansion sleeve is installed in the second conical hole, a first inner conical expansion sleeve is installed in the outer conical expansion sleeve, and the top of the outer conical expansion sleeve is higher than the top face of the bottom plate by a certain distance. The end of the cross rod is of a hollow cylinder structure, and a second inner conical expansion sleeve is installed in the hollow cylinder structure. The connecting pin sequentially penetrates through the top plate, the upper plane bearing, the second inner conical expansion sleeve, the lower plane bearing, the first inner conical expansion sleeve and the elastic body, and then the bottom of the connecting pin is fastened through a fastener.
