Background

The castor is a so-called movable caster, and the structure of the castor allows 360-degree horizontal rotation. The caster is a general term and comprises a movable caster and a fixed caster. The fixed caster has no rotating structure, can not rotate horizontally but can only rotate vertically. These two types of casters are commonly used in combination, for example, a cart has a structure with two fixed wheels at the front and two movable universal wheels at the rear, which are close to the pushing handrail. The universal wheel refers to a bracket which is arranged on a caster wheel and can horizontally rotate for 360 degrees in dynamic load or static load. There are a number of materials from which the castor is made, the most common being: nylon, polyurethane, rubber, cast iron and the like. The method is widely applied to various industries and fields such as mines, mechanical equipment, electronic equipment, medical equipment, engineering decoration, textile, printing and dyeing, furniture, logistics equipment, storage, turnover vehicles, cabinets, equipment, electromechanics, dust-free workshops, production lines, large supermarkets and the like. According to different uses, the bearing is divided into an iron core, an aluminum core and a plastic core, and the size of the bearing is 1-8 inches. Wherein the iron core and the aluminum core are generally heavy load-bearing wheels, and are often equipped with brake devices when in use.
