The Durastar 4" x 2" Rubber Wheel is engineered for dependable performance in demanding commercial and industrial environments. Featuring a high-quality rubber tread securely bonded to a glass-filled nylon core, this wheel is built to deliver long-lasting strength, traction, and maneuverability for medium-duty applications.
With a load capacity of up to 400 lbs, this wheel is ideal for carts, dollies, mobile workstations, and a wide range of transport equipment. The 3/4" standard roller bearing ensures smooth rolling with minimal resistance, reducing strain on operators and enhancing workplace productivity.
The rubber tread offers excellent grip on a variety of surfaces while minimizing noise and vibration, making it a preferred choice in settings where noise reduction and floor protection are priorities—such as warehouses, workshops, and healthcare facilities.
The wheel’s core is made from reinforced glass-filled nylon, which combines lightweight properties with the toughness needed to handle daily wear and tear. The bonding between the rubber tread and nylon hub is engineered to prevent separation over time, ensuring consistent, reliable operation.
All components are crafted to resist common workplace hazards such as moisture, debris, and impact, offering a maintenance-friendly solution with exceptional longevity.
This 4" x 2" wheel is highly versatile and suitable for use in both light and medium-duty mobility systems. Common applications include:
Backed by a reputation for durability and innovation, Durastar wheels are designed to exceed performance expectations in real-world environments. This wheel is manufactured to the highest quality standards, offering peace of mind and reliable performance across a wide range of applications.
Upgrade your mobility solutions with the Durastar 4" x 2" rubber wheel. Built for strength, designed for smooth performance—experience quality you can trust with every roll.
This 4" x 2" Rubber Glass-Filled Nylon Wheel – 400 lb is rated to 400 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 180°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.
