Caster wheels are an important component that significantly improves the functionality and usability of various objects, and Xiamen Yirong Hardware Co., Ltd. is committed to providing top - notch caster wheel products. In the aviation industry, caster wheels are used on ground support equipment such as aircraft tugs, baggage carts, and service carts. These wheels need to be able to handle the high loads and move smoothly on airport tarmacs and runways. Our caster wheels with high - strength alloy metal frames and high - performance rubber or polyurethane tires are designed for this demanding application. An airline that upgraded its ground support equipment with our caster wheels reported a reduction in equipment maintenance costs and an improvement in the efficiency of ground operations. In the marine industry, caster wheels are used on boat trailers, dock carts, and marine equipment storage racks. These wheels need to be resistant to corrosion from saltwater and able to operate on wet and uneven surfaces. Our caster wheels made of marine - grade stainless steel or corrosion - resistant plastic are ideal for this environment. A marina that used our caster wheels on their boat trailers found that the trailers could now be launched and retrieved from the water more easily, and the corrosion - resistant properties of the wheels extended their service life. In the art and museum industry, caster wheels are used on movable art displays, storage shelves, and conservation equipment. These wheels need to be quiet, non - marking, and able to move smoothly over delicate floor surfaces. Our caster wheels with soft - rolling polyurethane tires and precision ball bearings meet these requirements. A museum that installed our caster wheels on their movable art displays reported that the displays could be repositioned without damaging the floors or disturbing the artworks, allowing for more flexible exhibition layouts. Our caster wheels are also available with different types of mounting options, such as plate - mounted, stem - mounted, and hollow - kingpin - mounted, which allow them to be easily attached to different types of objects. We continuously invest in research and development to improve the performance and quality of our caster wheels, ensuring that they meet the evolving needs of our customers in various industries.
