Abstract

The invention relates to a steel-plastic universal wheel which has the characteristics of flexible rotation and easy walking and can not be damaged under the condition of large carrying capacity. The steel-plastic universal wheel comprises a universal wheel, wherein the tire of the universal wheel comprises a plastic tire core and a metal rim covered on the wheel surface of the plastic tire core;a bearing is embedded in a wheel center of the plastic tire core and positioned in a wheel carrier through a bearing shaft; and the wheel carrier is matched with a wheel seat through a pin shaft and the bearing and enables the wheel seat to rotate for 360 degrees. The invention has the following advantages: (1) the steel-plastic universal wheel has large carrying capacity, and can easily move androtate with the carried goods; (2) the steel-plastic universal wheel has simple structure, compact assembly and good tightness; (3) the wheel carrier adopts bearing rotation and has stable and flexible rotation; and (4) the steel-plastic universal wheel has long service life, and is especially suitable for use in places which is easy to impact by external force, and has large load capacity and very bad work environment.
