This mobile caster is tailor-made for mechanical and industrial workbenches, combining cast iron and nylon to create a versatile tool in industrial settings. The cast iron bracket is formed through high-temperature casting and precision machining, with an integrated structure that delivers exceptional load-bearing capacity. The robust material can withstand heavy pressure and severe impacts, remaining stable even when transporting heavy machinery without deformation or breakage. A dual-layer anti-rust coating on the surface effectively resists cutting fluids, corrosive gases, and other industrial contaminants, ensuring long-term reliability.   The high-quality nylon wheels are another key feature, with a high-strength fiber-reinforced structure embedded inside to enhance wear and tear resistance. Their excellent shock-absorbing properties cushion vibrations during movement, protecting the delicate components of equipment. The unique swivel design, paired with high-precision bearings, enables smooth and flexible steering, allowing even large workbenches to turn easily and position accurately. Additionally, the caster is equipped with a convenient braking mechanism—simply stepping on the pedal locks the wheel in place, preventing accidental sliding and ensuring safety in industrial operations. It fully meets the needs of various scenarios such as mechanical manufacturing and assembly processing, providing reliable mobility and stability for industrial production.
