The Industrial Line is the broadest, most-ordered caster category CasterHQ carries — the cold-formed, heat-treated steel casters that show up under dollies, waste trucks, warehouse trucks, floor trucks, and shop carts in essentially every manufacturing operation. It spans medium duty through medium-heavy duty, every common wheel material, and every standard mounting pattern.
This is not a specialty category. It’s the default — the casters you reach for when the application is “a sturdy cart that needs to roll reliably for years” and there’s no exotic requirement driving you toward stainless, high-temp, or extreme-duty. The brands inside it — Albion’s 16 and 62 Series, Hamilton, and others — have been refining this exact category for decades.
The fork and top plate are cold-formed steel — stronger than stamped, more economical than forged. The category’s defining construction.
The kingpin and nut are heat-treated for a longer swivel life under daily duty — the detail that separates a real industrial caster from a hardware-store one.
The capacity sweet spot runs roughly 300 lb up to 1,500 lb per caster — the range that covers the large majority of plant-floor carts.
Plate, stem, and expanding adapter mounts in all the common bolt patterns — built to drop into existing equipment.
| Wheel | Best for | Trade-off |
|---|---|---|
| Polyurethane on iron | Most plant floors — capacity plus floor protection | Costs more than bare iron |
| Cast iron / semi-steel | Maximum capacity, rough floors, debris | Marks floors, rolls loud |
| Mold-on rubber | Quiet roll, cushioned ride, finished floors | Lower capacity, can flat-spot static |
| Phenolic | Oil/solvent areas, low rolling resistance | Hard, noisy, brittle under impact |
| Polyolefin / nylon | Wet areas, chemical resistance, economy | Lower capacity than iron-core |
