The four-bearing mute PU universal wheel comprises a support, a double-shaft stabilizer, rivets and a double-shaft balancer, an insertion opening is formed in the upper surface of the support, a partition ring is arranged on the inner wall of the insertion opening, the double-shaft stabilizer is installed in the insertion opening, an insertion rod is inserted into the double-shaft stabilizer, an annular groove is formed in the upper portion of the surface of the insertion rod, and a fixing ring is connected into the annular groove in a sleeved mode. The rivet is connected with the support in an inserted mode and penetrates through the support, the rivet is sleeved with the double-stable sleeve, the surface of the double-stable sleeve is sleeved with the support, the surface of the double-stable sleeve is sleeved with the double-shaft balancer, and the surface of the double-shaft balancer is sleeved with the skateboard wheel. The inserting rod is connected with the first bearing and the second bearing in an inserted mode, double supporting and positioning are conducted on the inserting rod, the universal wheels are installed on the trolley through the inserting rod, it is guaranteed that the inserting rod cannot shake, and the trolley is more silent during turning. The skateboard wheel is assembled through the third bearing and the fourth bearing, parallel supporting of the skateboard wheel is achieved, the supporting force on the skateboard wheel is more sufficient, and the skateboard wheel rolls more stably and silently.
