Caster wheels with ball bearings from Xiamen Yirong Hardware Co., Ltd. are engineered for ultra-smooth movement, reducing friction to minimize effort when pushing or pulling loads. These wheels feature precision ball bearings—sealed to resist dust, moisture, and debris—that enable the wheel to rotate with minimal resistance, even under heavy loads (50-5,000kg). Constructed from materials like polyurethane, rubber, or steel, they suit applications from office chairs and furniture to industrial carts and medical equipment. The ball bearings distribute weight evenly across the wheel hub, reducing wear and extending service life, even after 100,000+ rotation cycles. Swivel models include bearings in the raceway, ensuring 360° rotation without binding, making them ideal for maneuvering in tight spaces like office cubicles, laboratory benches, or factory aisles. Whether rolling over carpet, tile, or concrete, these caster wheels deliver effortless mobility, reducing operator fatigue and enhancing efficiency in both light and heavy-duty applications.
