The invention discloses an adjustable universal wheel set. A wheel shaft is arranged at the center of a wheel, wherein two ends of the wheel shaft extend to two sides of the wheel; one end of the wheel shaft is sleeved with a self-aligning roller bearing; bearing sleeves are arranged on the outer surface of the self-aligning roller bearing and the outside of the section of the wheel shaft; and a plurality of through holes are formed in the annular surfaces of the bearing sleeves. Openings of 130-160 degrees are formed in an angle bearing box; a plurality of through holes are formed in the annular surface of the angle bearing box; and the bearing sleeves are movably connected with the angle bearing box through bolts. With a vertical center line of the wheel as a symmetric axis, the structures of two sides of the wheel are symmetric; bolts are arranged in through holes A of a support lug A and through holes B of a support lug B of the angle bearing box; and the angle bearing box is connected with a frame by the bolts. The adjustable universal wheel set is easy and fast to exchange; the skewness and the perpendicularity of the wheel can be controlled; rail gnawing of the wheel is not easily caused; the abrasion of the wheel edge and a track is alleviated; and the manufacturing cost is low.
