Tough As Nails Heavy Duty Swivel Caster With 12 X 3 Inch Polyurethane Tread On Solid Cast Iron Wheel Featuring 3 4 Inch Sealed Precision Ball Bearings For Smooth Rolling Applications

Single Pack: Heavy Duty Swivel Caster With 12 Inch Wheel
✔️ 3/4 inch sealed bearing, cast iron core, quick plate mount

This single heavy duty swivel caster pairs a polyurethane tread over a solid cast iron wheel to handle demanding shop floors, warehouse racks, and workshop benches where steady rolling matters most.

✅ Polyurethane rubber tread rolls quiet on concrete and shop tiles without marring flat finishes
✅ Solid cast iron wheel frame carries heavy tools and material carts past standard plastic hubs
✅ 3/4 inch diameter bore accepts mounting studs and hardware for fast installation
✅ Full swivel design turns tight corners quickly while locking brakes stay optional for safety

💡 Why pick sealed ball bearings for heavy duty swivel casters over open bushings?
Sealed units keep grit out so your cart stays handy and smooth under load.
- Closed grease seals stop dust and metal shavings from eating up rotation speed
- Precision matched steel races hold alignment longer when hitting curb lips daily
- Zero play in the hub stops wobble so you can steer heavy pallet jacks without fighting the handle
