All measurements indicate the wheel diameter by the tread width.
The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size.
When replacing existing casters, select the closest plate size and verify bolt-hole compatibility.
BHP = Bolt Hole Pattern, shown under each plate.
High-heat casters survive the temperatures that destroy ordinary wheels — oven and kiln lines, heat-treat and powder-coat operations, foundry and forge environments. Phenolic, glass-filled nylon, cast iron, and steel wheels with high-temp bearing grease and heat-stable rigging, rated up to 9,000 lb per caster.














































Hamilton high-heat casters use all-metal forged steel wheels for the hottest service and Plastex phenolic for moderate-temperature carts. Match the wheel to your continuous oven, kiln, or heat-treat temperature, then size at a 25% margin.
| Series / Config | Size | Capacity | Wheel | Best For |
|---|---|---|---|---|
| High-Heat Forged Steel | 6" to 8" | up to 9,000 lb | Forged steel, continuous to 750F | Heat-treat racks, furnace and kiln carts |
| High-Temp Metal | 6" to 8" | up to 6,000 lb | High-temp cast metal | Foundry transfer, sustained radiant heat |
| Plastex Phenolic | 5" to 8" | up to 3,000 lb | Plastex phenolic, continuous to 475F | Baking line and oven carts, moderate heat |
| Phenolic Light Cart | 4" to 6" | up to 1,200 lb | Plastex phenolic | Proofing racks, bakery rack carts |

Add cart weight plus payload, divide by the number of casters, then add 25% for uneven loading and door thresholds. With four casters, treat three as carrying the load so one swivel does not become the failure point. The line tops out at 9,000 lb per caster on forged steel.
Forged steel runs continuously to 750F and survives direct furnace and kiln exposure where no polymer can. Plastex phenolic handles continuous service to 475F for oven and baking lines but should not dwell inside a hot oven under load. Match the wheel to the highest sustained temperature the caster sees, not the average.
Specify a heavy top-plate rig sized to the equipment frame and verify the bolt pattern against your existing mount. High-heat duty calls for a robust kingpin or kingpinless swivel rated to the wheel capacity. Sealed bearings are not used in the hot zone because grease breaks down, so confirm the bearing and lubricant are rated for your temperature.
Heat-treat, baking, and foundry floors expose casters to thermal cycling, scale, and dropped debris. All-metal wheels shrug off scale and resist flat-spotting under heat soak. For carts that cycle between a cold staging area and a hot zone, inspect swivel raceways on a set schedule.
Forged steel and high-temp metal wheels run continuously to 750F, covering most heat-treat, kiln, and furnace cart duty, while Plastex phenolic handles continuous service to 475F for oven and baking lines. Rate the caster to the highest sustained temperature it sees, and confirm the bearing and grease are rated for that temperature too.
The Hamilton high-heat line reaches up to 9,000 lb per caster on a forged steel wheel, and Hamilton custom-engineers higher capacities for heavy furnace charge cars on a quote basis. Call 844-439-4335 with your load, temperature, and frame details for a cross-reference.
Choose forged steel for the hottest service, continuous to 750F, and for foundry and furnace exposure. Choose Plastex phenolic for oven and baking carts up to 475F continuous, where it rolls quieter and is easier on floors than steel.
Not in the hot zone, because sealed-bearing grease breaks down above its rated temperature. High-heat casters typically use a plain, sleeve, or high-temperature bearing matched to the operating temperature, so confirm the bearing and lubricant rating with us before ordering.
Yes. Hamilton Caster has manufactured in Hamilton, Ohio since 1907, and the high-heat forged steel and phenolic lines are built there. CasterHQ is a Hamilton authorized distributor shipping from Mansfield, Texas.
We stock the most common high-heat forged steel and phenolic sizes for same or next-day shipment, and less common temperature-rated or custom rigs ship from the Hamilton factory on a short lead time. Call 844-439-4335 for stock status and lead time on your spec.
