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.

The 8 inch diameter rolls over obstacles and seams with less effort and spreads heavy loads across a larger contact patch, while the solid metal wheel carries enormous weight and tolerates heat, oil, and chemicals. For the heaviest carts that also need to roll over rough or debris-strewn floors, 8 inch metal casters combine high capacity with easier rolling. As with all metal wheels, they are best on shop floors, not finished surfaces.

8 inch metal casters in this collection carry 900 to 5,400 lbs per caster, in swivel, rigid, and locking brake versions. The big wheel makes heavy carts easier to move and start. Build a set with two rigid and two swivel casters for stability and steering, and add brakes where the load must stay parked. Choose polyurethane or rubber for finished floors.
