Designed to outperform in extreme environments, the Durastar 4" x 2" Hi-Temp Glass-Filled Nylon Wheel is your reliable solution for high-temperature mobility applications. Whether in industrial ovens, autoclaves, food production, or material handling, this wheel offers unmatched resilience and smooth operation under pressure.
This heavy-duty wheel is manufactured using glass-filled nylon, a reinforced material engineered to maintain structural integrity even in elevated temperatures. Unlike standard wheels that degrade under thermal stress, Durastar’s proprietary composition delivers reliable, long-term performance where other wheels fail.
The wheel features a 1-3/16" plain bore coupled with a 3/4" standard roller bearing, ensuring fluid rotation and low resistance in both manual and motorized applications. These components are precision-fit for enhanced efficiency and minimal maintenance, even in continuous-use scenarios.
Supporting up to 800 lbs, this 4" x 2" wheel is built for stability and strength. Its size provides superior floor contact and maneuverability while minimizing wear on flooring surfaces—ideal for environments with sensitive or high-traffic flooring.
This hi-temp nylon wheel is widely used in:
Backed by the trusted engineering standards of Durastar, this wheel offers the perfect combination of durability, performance, and precision. Each component is carefully crafted to meet the rigorous demands of modern industrial and commercial environments, reflecting Durastar's reputation for quality and innovation.

This 4" x 2" Hi-Temp Nylon Wheel – 800 lb is rated to 800 lbs per wheel. Divide the total load across the number of wheels in your rig and keep working loads within about 75-80% of the rating for continuous use.
This is a Nylon wheel. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.
4" diameter x 2" tread width. Verify your axle diameter and hub/bore length against your existing wheel before ordering.
Yes. Most wheels can be paired with a swivel or rigid rig to build a complete caster. Tell us your mount and load and we will spec the rig - request it on our bulk pricing page.
Rated for Up to 550°F. Operating outside the rated range can shorten wheel life and reduce capacity.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
Application guidance for load margin, wheel materials, and swivel construction. Confirm ratings against your duty cycle, floor, and temperature before final spec.
Treat published load capacity as a continuous working limit, not a one-time peak. Divide total loaded cart weight (product + rack + fixtures) by the number of casters that share the load, then size so that working load per caster stays at or below about 75% of the rated capacity (a common ~25% margin). On four-wheel oven racks, uneven floors and thermal growth can shift load to two or three casters; if your process routinely parks on imperfect floors, engineer for three-caster support rather than perfect four-way share. Confirm ratings at your process temperature — heat softens many wheel compounds and can lower usable capacity versus room-temperature catalog numbers.
Bypass standard polyurethane when continuous or cyclic wheel temperatures exceed the urethane compound’s published service range (often well below typical bake / washdown-after-heat zones). Spec glass-filled nylon or phenolic (or other high-temp tread systems on the PDP) when racks enter ovens, proofers, or wash tunnels where tread softening, bond failure, or flat spots would appear with PU. Match the wheel to the hottest surface the tread sees, including residual heat after exit, and verify chemical exposure (cleaners, fats, steam) against the material notes on this product. When in doubt, ask for the temperature and duty cycle — we will confirm whether this SKU or a high-temp alternate is the right call.
A traditional kingpin clamps the swivel assembly through a single axial fastener. Repeated side thrust from towing, tugger lines, or AGV path corrections loads that pin and the raceway faces in ways ordinary cart steering does not. Over time that shows up as elongated kingpin holes, brinelled races, or loose swivels. Kingpinless (or forged integrated) raceways distribute thrust through a continuous race path instead of relying on that central pin — better suited when side loads are planned into the duty cycle. Oven-rack and high-temp lines still need the correct wheel material first; upgrade the swivel construction when towing or powered side loads are part of the application, not only when heat is.
