High-temperature wheels in hi-temp phenolic, glass-filled nylon, epoxy and steel. Listed ratings run from 250°F to 800°F depending on material, so check each listing against your heat.
Start with the hottest spot the wheel will see, then match material. Ratings below come from product fields on this page [S1]. Maker guidance on dry vs moist heat is in the sources [S2][S3].
| Material | Listed temperature | Sizes and loads here |
|---|---|---|
| Hi-temp phenolic | Up to about 475°F continuous (some Durastar listings note 525°F intermittent) | 3 x 1-1/4 in at 200 lb to 12 x 3 in at 2,600 lb |
| Glass-filled nylon | Up to about 425°F continuous; some 2 in wide listings to 550°F intermittent | 4 and 5 in narrow at 300 lb; 4 to 8 x 2 in at 800 to 1,400 lb |
| Epoxy oven-rack (Quad X) | -20 to 475°F where listed | 4 x 1-1/2 in, 300 to 500 lb |

A high-temp wheel still needs a rig, axle, and grease that survive the same zone. If only the wheel is heat-rated, keep the fork out of the hot cell or choose a high-temp bearing package on the listing.

Ductile and machined steel listings show about 750 to 800°F. Plastic options top out lower: roughly 475°F continuous phenolic and up to about 550°F intermittent on some glass-filled nylon listings.
Phenolic for dry heat on smooth floors. Glass-filled nylon when moisture or steam is present. Confirm the listing temperature and bearing package.
From 200 lb on small hi-temp phenolic to 6,000 lb on ductile steel on this page.
No. Standard polyurethane is commonly limited near 180°F. Use the materials on this page or a verified high-temp listing.
