The single-bearing shaftless mute double-row trundle comprises a decorative cover, a main body, an outer wheel support A and an outer wheel support B. Outer wheels are arranged on the outer surfaces of the outer wheel support A and the outer wheel support B respectively, and the main body rotates relative to the outer wheel support A and the outer wheel support B; the automobile hub is characterized in that a supporting sleeve is arranged on the outer surface of the decorative cover, a bearing is arranged on the outer ring of the supporting sleeve, the body is arranged on the outer ring of the bearing, and the outer wheel support A and the outer wheel support B are arranged on the left side and the right side of the body respectively; an outer wheel bracket neck bush A is arranged on the left side of the bearing, and an outer wheel bracket neck bush B is arranged on the right side of the bearing; the caster is simple in structure, reasonable in design, long in service life, fashionable and high-end in appearance, convenient to assemble and low in cost, the relative price of the caster can be greatly reduced, meanwhile, the flexibility and bearing capacity of supporting pieces on the two sides of the bearing are improved, and the service life of the supporting pieces on the two sides of the bearing is prolonged; compared with a product which is manufactured by our company and uses two bearings for a single trundle abroad, the trundle is more in line with the policy of energy conservation and emission reduction advocated by China.
