Engineered for heavy custom machinery, thick-based industrial frames, and rugged tubular equipment, our 151-200 kg (332-440 lbs) bolt hole casters deliver high-capacity through-bolt fastening. Featuring an extra-heavy-duty hollow kingpin designed to prevent crushing under massive operational weights, they support secure custom bolt installation. Built strictly in sizes of 2 inches and above with heavy-load, non-marking treads, they ensure smooth mobility and reliable locking options. Can’t find what you need? Contact us for guidance.
