Hamilton Casters w/ Metal Wheels · Up to 1,250 lb · 5"–8" · Cast Iron

Diameter: 5, 6, 8 inTread: 2 inCapacity: up to 1,250 lb

Industrial tread compounds casters here serve warehouse carts, racks, and everyday plant fixtures. Expect wheel diameters 5, 6, 8 in, plate-mount frames, and capacities 1,250 lb. Confirm stem length and thread pitch on stem mounts so the shoulder seats flush in the boss. Softer treads quiet finished floors; harder compounds last longer on chips, heat, and rough concrete. These medium-duty options cover everyday warehouse carts, racks, and everyday plant fixtures without jumping to extreme forged series.

Series M Metal Wheels: Superior Quality & Durability

Industry-Leading Metal Wheels | Capacities from 250 to 7,000 lbs

Hamilton's Renowned Metal Wheels

Hamilton's Series M Metal Wheels stand at the forefront of the industry with a comprehensive range of sizes and capacities, from 250 to 7,000 lbs. Renowned for their robust construction, most of these wheels are crafted from high-quality cast iron, with smaller sizes in sintered iron, ensuring unparalleled durability.

Innovations in Durability and Design

Over the last three years, our most popular metal wheel sizes have undergone significant upgrades. These improvements include larger hubs and a reduction in scrap metal content, exemplifying our commitment to providing the highest quality and most durable metal wheels in the industry.

Advanced Features for Enhanced Performance

All metal wheels exceeding 5" in diameter are equipped with lubrication fittings in the hubs, a feature that ensures longevity and ease of maintenance. For smaller wheel sizes, we recommend lube axles. Please note that non-standard bores may incur an additional charge, and we offer customized solutions for close tolerances upon request.
