Industrial Casters. Engineered for Spec.
High temperature caster wheels are engineered for ovens, kilns, furnaces, and industrial processes where standard wheels fail. Available in cast iron, forged steel, and specialty compounds rated from 400°F to 1,200°F. Sizes 2" to 8", rated 100 to 1,000 lbs per caster.
Cast iron and forged steel caster wheels are designed for temperatures from 400°F to 1,200°F.
Phenolic resin handles up to 350–400°F. Above that threshold, metallic wheels — cast iron, ductile iron, and forged steel — are required. Cast iron is the workhorse spec for 400°F–800°F kiln and oven applications. Forged steel is specified for the most extreme environments above 800°F.
Match wheel material to peak oven temperature, then specify high-temp grease bearings for the full thermal range.
For conveyor ovens at 400°F–600°F, cast iron wheels with high-temp grease bearings (rated 450°F+) are the standard spec. Confirm the bearing housing material: standard zinc or aluminum housings soften above 400°F; specify steel or cast iron housings for high-heat applications.
Yes — forged steel and cast iron casters are designed for continuous furnace operation.
Continuous furnace applications require casters that tolerate thermal cycling (repeated heating and cooling), radiant heat from furnace walls, and the weight of furnace furniture or metal billets. Specify sealed high-temp bearings and confirm the caster housing is steel — do not use standard zinc-plated housings in continuous furnace environments.
Cast iron handles up to 800°F and is suitable for most industrial oven and kiln applications. Forged steel handles 1,200°F+ for extreme environments.
Cast iron is more economical and available in a wider range of sizes. Forged steel costs more but provides superior impact resistance and thermal stability at very high temperatures. For most powder coat ovens, ceramic kilns, and heat treatment furnaces, cast iron is adequate. Forged steel is specified for forge shops, glass annealing furnaces, and metal heat treatment above 800°F.
Step 1: Determine peak operating temperature — this determines wheel material (phenolic ≤350°F, cast iron ≤800°F, forged steel >800°F). Step 2: Calculate load per caster with 1.3 safety factor, then derate 20% for sustained high heat. Step 3: Confirm bearing grease rating matches or exceeds operating temperature. Failure to match grease to temperature is the #1 cause of high-temp caster failure.
