High-Temp Glass-Filled Nylon Wheels

These high-temp glass-filled nylon wheels are the better pick for moist heat, washdown, and humid plant floors where phenolic struggles with water. Wheels in this collection range from about 300 to 1,400 lb per wheel. Titles split between about 425°F and 550°F intermittent service. Most of the shortlist lists 550°F. They also cover many oven and hot-cart jobs where soft rubber would fail. Glass-filled nylon is a child of the broader high-temperature wheels hub. Soft polyurethane on aluminum (~85 Shore A) or TPR is not the usual pick for oven heat. Match temperature rating, bore, and diameter before you order so the new wheel seats correctly. Capacities below are per wheel as labeled. Dry phenolic aisle: phenolic wheels. Broader heat aisle: high temperature wheels. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you place your order today.

Moist heat vs dry heat

Glass-filled nylon tolerates moisture that damages phenolic. Prolonged dry oven heat can still damage GFN, so pick phenolic for dry continuous heat and GFN when steam or washdown is in the cycle [S2][S3].

Band on this page Listed temperature Loads
Narrow 4 and 5 in Up to 425°F About 300 to 350 lb

Bearing and fork reminder

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