5" x 1-1/2" High Temp Glass-Filled Nylon Wheel – 700 lb | CasterHQ

5" x 1-1/2" High Temp Glass-Filled Nylon Wheel — 700 lb Capacity The CasterHQ HTGFN5X112 is a 5" diameter x 1-1/2" wide glass-filled nylon wheel rated 700 lb per wheel, running 475°F continuously and 550°F intermittently. Glass-filled nylon runs in both dry and moist heat, which is what separates it from phenolic, and most buyers specify it for the moist side: bakery oven racks, smokehouse trucks, proof boxes, autoclave carts, and steam wash-down lines where a polyurethane or rubber wheel would soften, delaminate, or flat-spot. It is impervious to most chemicals, solvents, oils, salt, alkalines, and water, and it holds capacity through repeated heat cycles.

Best For Bakery oven racks and rack ovens cycling through 400°F+ bake chambers Smokehouse and moist-heat cook trucks in protein and further-processing plants Autoclave and sterilizer carts in medical device and pharma production Proof boxes and retarder cabinets moving between humid heat and cold storage Wash-down and steam-clean lines where wheels are sanitized in place Replacement for failed phenolic on carts that swell, chip, or crack from moisture Engineer Tip: Glass-filled nylon has a hard tread and belongs on smooth floors. On rough concrete or over floor obstructions the service life drops fast, and the impact loading is what cracks the hub, not the heat. Where the cart crosses a threshold or a floor drain grate, shield the wheel from direct heat intake and step up to a 2" tread instead of adding capacity elsewhere. What is this wheel used for? It replaces the wheels on carts, racks, and trucks that live inside heat. The 5" x 1-1/2" size is the common swap on bakery oven racks and smokehouse trucks where a 4" wheel no longer clears floor debris or the operator wants easier roll-out under load. At 700 lb per wheel, a four-wheel rack carries 2,800 lb theoretical, and specifying to roughly 75% of that leaves margin for shock loading at door thresholds. What is the load capacity? 700 lb per wheel at room temperature. De-rate 20% to 560 lb per wheel for sustained operation at maximum rated temperature or in sustained sub-freezing service. Rate the assembly on three wheels, not four, since floors are rarely flat enough to load all four evenly. Does it have a bearing or brake option? This wheel ships plain bore with a spanner bushing. It is a wheel only, not a complete caster, so the brake lives in the rig you mount it to. If you need the finished assembly, the 5" x 2" High Temp Glass-Filled Nylon Swivel Caster is available with top-locking brake and bolt-on swivel lock on a 4" x 4-1/2" plate. Glass-filled nylon vs. high-temp phenolic Glass-filled nylon runs in both dry and moist heat. High-temp phenolic runs dry heat only. That is the whole decision. Phenolic absorbs water in steam, humid bake, and wash-down environments, then swells, delaminates, and chips, so it has no place in a smokehouse, autoclave, proof box, or sanitation line. Glass-filled nylon handles those and handles dry radiant heat as well, which makes it the wider-envelope wheel and the safer spec when one cart sees more than one condition. Most buyers land on nylon for moist-heat duty specifically, but if your only concern is dry radiant heat you can compare high-temp phenolic wheels on cost. How does it compare to the 4" and the 5" x 2"? Same family, different footprint and resin grade. The 4" x 1-1/2" high temp glass-filled nylon wheel is a moist-heat wheel rated 300 lb and 425°F for 30 minutes maximum. This 5" runs the higher-grade resin at 475°F continuous. Step to the 5" x 2" glass-filled nylon wheel at 1,000 lb when the load is the constraint rather than the clearance. Frequently Asked Questions What temperature can this wheel handle? 475°F continuously and 550°F intermittently, with a low-end rating of -40°F. Can it run in dry heat as well as moist heat? Yes. Glass-filled nylon handles both dry and moist heat. High-temp phenolic is a dry-heat-only wheel, which is why nylon is the safer spec when a cart sees more than one condition. How much weight will one wheel hold? 700 lb per wheel at room temperature. De-rate by 20% for sustained maximum heat or sustained cold. Is this a complete caster or just the wheel? Wheel only. It ships plain bore with a spanner bushing and mounts into your existing rig. Will it work in a steam or wash-down environment? Yes. Glass-filled nylon is impervious to water, steam, most chemicals, solvents, oils, salt, and alkalines, which is why it outlasts phenolic in sanitation-heavy plants. Is it non-marking? Yes. It is non-marking and non-sparking, and it runs quieter than a steel or cast iron wheel. Do you offer volume pricing? Yes.
