High-temperature casters operate above 200°F, where polyurethane fails. Phenolic resin handles up to 475°F continuous; cast iron and forged steel handle 800°F+; specialty ceramic-bearing configurations handle 1,000°F+ for kiln cars. Bearings shift to high-temp greases or graphite-bushed designs. Construction is fully welded steel — no PU components, no plastic raceways. Specifying these requires telling us the actual operating temperature and dwell time at temperature.
Specifications
| Phenolic resin | Up to 475°F continuous |
|---|---|
| Cast iron / forged steel | 800°F+ continuous |
| Ceramic-bearing kiln | 1,000°F+ for kiln-car applications |
| Bearings | High-temp grease or graphite-bushed |
Common Applications
- Bakery oven racks and proofing carts
- Autoclave and sterilization carts (medical, food, pharma)
- Industrial drying ovens and curing lines
- Foundry ladle and slag-pot transfer
- Ceramic kiln cars and heat-treat furnace charge cars
- Powder-coat oven racks
When to Choose High-Temperature Casters
- Equipment is specified to operate above 200°F
- Equipment cycles in/out of high-temp environments (oven racks)
- Floor and ambient conditions at temperature degrade standard PU
- Process audit (HACCP, validated sterilization) requires documented temperature handling
