Description

New material bearing sleeve cover truckle Technical Field The utility model relates to the technical field of casters, in particular to a novel material bearing sleeve cover caster. Background The product castor is a small wheel arranged at the bottom of equipment, machinery or furniture, and is mainly used for facilitating moving objects and improving mobility, flexibility and bearing capacity. Casters are widely used in industrial, commercial and domestic environments, such as factory equipment, carts, medical equipment, furniture, etc., where the wheels are typically composed of wheels, brackets and connectors. According to different use demands, casters with different materials, sizes and bearing capacities can be selected. The core function of the device is to enable the device or the object to move easily, reduce the burden of manual carrying and adapt to various moving scenes. In the prior art, in the process of installing the trundle bearing, a rivet is needed, and a threaded hole is needed to be formed in the rivet for installing the wave disc at a corresponding position, but the perpendicularity of the joint surface is difficult to ensure by rivet thread processing, and the rivet is not beneficial to mass production of the rivet.
