High Temperature Bakery & Oven Rack Casters

OVEN RACK • BAKERY RACK • PAN DOLLY • PROOFER CART

High temperature casters engineered for bakery racks, oven racks, pan dollies, and proofing carts operating in elevated heat. These are specified when standard wheels fail from thermal softening, flat-spotting, or bearing seizure during repeated bake cycles.

Heatwave™ 500°F casters (Made in USA): glass-filled polymer wheels with wave-designed webbing intended to improve heat dissipation for high-temperature cycling (model dependent).

Featured: 4" Heatwave™ 500°F Bakery Rack Casters

HS40P2HWO — 4" Heatwave 500°F Swivel Caster (Zinc-Plated) Made in USA · glass-filled polymer · wave webbing · swivel only (no brake) SSHS40P2HPB — 4" Heatwave 500°F Swivel Caster (Stainless Steel) Made in USA · stainless rig for wash-down/corrosion environments · see product page for brake availability

Fitment check: Confirm your rack uses a 4 1/8" × 3 1/8" top plate and matching bolt-hole spacing before ordering.

Which one should you buy?

Zinc-plated (HS40P2HWO): general bakery/oven rack use where corrosion is not the primary issue.
Stainless (SSHS40P2HPB): wash-down, humidity, or corrosive cleaning environments.

Selection Guidance

What fails first in bakery & oven rack caster systems

Common failure modes include wheel softening or deformation, flat-spotting during cooling, and bearing seizure when lubricants break down. High-temperature casters are designed to preserve rolling performance through repeated bake cycles.

When to choose Heatwave 500°F

Choose Heatwave when you need higher thermal headroom, frequent oven cycling, or improved heat dissipation characteristics. For wash-down or corrosion exposure, choose stainless.

When you need a brake

If racks must hold position during loading/unloading, choose a configuration with a brake. If you don’t see a brake on the product page, contact us and we’ll match a compatible brake option.
