8 Inch Metal Casters

These range from about 900 to 5,400 lbs per caster depending on the rig. The large solid metal wheel carries heavy loads and rolls easily over obstacles. Divide your total load across all casters and add a safety margin.

The larger 8 inch diameter rolls over floor seams, debris, and thresholds with less effort and spreads heavy loads better, reducing push force on loaded carts. For the heaviest carts on rough floors, the bigger wheel makes the job easier and safer.

On bare concrete or steel, no. On finished floors, metal wheels can score or crack softer surfaces under heavy load. For floor protection, choose polyurethane or rubber. Reserve metal casters for shop floors and industrial concrete.

Yes. Metal wheels tolerate far higher temperatures than rubber or polyurethane, making them common near ovens and foundries. For sustained heat, confirm the bearing and seals are also rated for the temperature, not just the wheel.
