The Durastar 4" x 2" High-Temp Phenolic Wheel is expertly designed to handle the intense demands of industrial and high-heat environments. Whether you're outfitting equipment for use in autoclaves, bakeries, or manufacturing plants, this wheel provides the perfect balance of strength, heat resistance, and smooth operation.
Constructed from high-quality phenolic resin, this wheel is capable of withstanding extreme temperatures without deforming or cracking. Its robust design ensures lasting performance in environments where standard wheels would fail. With a 600 lb load capacity, it is built for reliability and heavy-duty use.
Equipped with a 1-3/16" plain bore and a standard 3/4" roller bearing, this wheel offers easy integration into a wide range of axle and rig assemblies. The roller bearing delivers low rolling resistance and consistent movement, even under weight or prolonged use.
The phenolic material is highly resistant to oils, greases, solvents, and water—making this wheel an ideal choice for environments that require frequent wash-downs or where exposure to harsh substances is unavoidable. This ensures both product longevity and safety in the workplace.
From commercial bakeries and food processing facilities to industrial manufacturing plants and cleanroom equipment, the Durastar phenolic wheel meets a wide range of operational needs. Its heat-resistant and chemically resilient build makes it a reliable solution for demanding industries.
Backed by Durastar’s reputation for engineering excellence, this high-temperature wheel is a testament to quality craftsmanship and performance integrity. When performance matters most, trust Durastar to deliver wheels that stand up to heat, weight, and wear.
Make the switch to Durastar’s high-temp phenolic wheels and experience the confidence that comes with long-lasting mobility solutions. Ideal for high-heat, heavy-duty environments—engineered to perform where others fail.
This 4" x 2" Phenolic Industrial Replacement Wheel – 600 lb is rated to 600 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 High Temp Phenolic wheel. Phenolic carries high loads on smooth, hard floors and tolerates heat, but transmits more shock than an elastomer tread.
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 525°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.
