CasterHQ industrial caster wheels and replacement wheels — 402 SKUs covering every major wheel material: polyurethane (on iron, aluminum, polyolefin), phenolic, hard rubber, thermo rubber, nylon, steel, polyolefin, and specialty formulations. 1-7/16" through 16" diameters, 80 to 7,600 lb per wheel. The widest stocked industrial wheel inventory in the U.S. at our Mansfield, TX facility.
Caster wheels are the replaceable rolling component of a caster: the tread, hub, and bearing that carry the load, sold separately from the swivel or rigid frame. Diameters run 1-7/16" to 28" with per-wheel capacities from 80 lb to 7,600 lb. To size a replacement, match three specs from the worn wheel: diameter x width, bore size, and hub length, then pick the tread material for your floor. Need the complete assembly instead? Shop industrial casters with the wheel and frame already matched.
Every industrial wheel material we stock, with the capacity range, best application, and trade-offs. Wheel material is the single most important spec on a caster — it determines load capacity, floor compatibility, noise level, and service life.
| Wheel Material | Capacity Range | Floor Compatibility | Best Application |
|---|---|---|---|
| Polyurethane on Iron | 500 to 5,000 lb | Hard floors, non-marking | Heavy industrial, manufacturing |
| Polyurethane on Aluminum | 300 to 1,200 lb | Hard floors, non-marking | Medium industrial, lighter weight |
| Polyurethane on Polyolefin | 200 to 800 lb | Hard floors, non-marking | Light to medium, lower cost |
| Phenolic | 300 to 1,500 lb | High-temp tolerant 350F+ | Bakery, oven, dish room |
| Hard Rubber | 200 to 600 lb | Smooth floors, quiet | Office, retail, light commercial |
| Thermo Rubber (TPR) | 180 to 600 lb | Soft floors, very quiet | Hospital, food prep, residential |
| Nylon | 250 to 1,200 lb | Hard floors, chemical-resistant | Food contact, wash-down, chemical |
| Semi-Steel / Steel | 500 to 5,000 lb | Industrial concrete, dock | Heavy mfg, forging, high-temp |
| Forged Steel | 2,000 to 7,600 lb | Industrial concrete | Extra heavy mfg, kingpinless |
| Cast Iron | 500 to 4,000 lb | Industrial concrete | Heavy mfg, abuse-resistant |
| Polyolefin | 200 to 800 lb | Smooth floors, dry conditions | Light to medium retail/commercial |
| Pneumatic (Air-Filled) | 100 to 7,600 lb | Outdoor, uneven, rough | Hand trucks, outdoor equipment |
Total equipment + load weight divided by number of wheels = per-wheel requirement. Add 25 percent headroom for shock loads. A 4-wheel cart at 2,000 lb total needs at least 625 lb per wheel.
Smooth concrete and tile: polyurethane or hard rubber. Soft floors and noise-sensitive: TPR rubber. High temp: phenolic. Chemical/food contact: nylon. Heavy industrial: steel or cast iron. Outdoor rough: pneumatic.
Larger wheels roll easier over thresholds, dock seams, and uneven floors. Standard cart wheel: 3-5 inches. Heavy industrial: 6-8 inches. Outdoor: 10 inches or larger.
Solid wheels (no hub) cap around 800 lb. Aluminum hubs handle 1,200 lb. Iron and steel hubs handle 2,000-7,600 lb. Match the hub to your maximum load.

Measure the worn wheel, not the caster frame. Three measurements identify any replacement wheel:
Measure across the wheel face (diameter) and across the tread (width). Common industrial sizes: 3" x 1-1/4", 4" x 2", 5" x 2", 6" x 2", 8" x 2". Larger diameters roll easier and clear thresholds; wider treads carry more load.
The axle hole diameter: 3/8", 1/2", 5/8", 3/4", or 1". Measure the existing axle bolt with calipers. A wrong bore will not seat on the axle.
Overall width at the wheel center, bearing face to bearing face. The hub must fill the frame's inside width or the wheel walks side to side on the axle and wears the bearing out early.
Replacing wheels on mobile equipment? See hand truck wheels, keyed drive wheels, and track wheels for application-specific fits.
Engineer tip: If a polyurethane tread is separating from its iron core, check the load math before reordering the same wheel. Tread separation at under 70 percent of rated capacity almost always means shock loading from dock transitions, elevator lips, or drops. Step up to a harder durometer poly on iron, or switch to forged steel and solve it permanently.
CasterHQ stocks 402 caster wheel configurations at our Mansfield, TX facility — the widest industrial replacement wheel inventory in the U.S. Polyurethane, phenolic, hard rubber, TPR, nylon, steel, cast iron, polyolefin, pneumatic. 1-7/16" through 16" diameters. 99 percent of orders ship same or next business day.
Depends on your application. Polyurethane is the most versatile (non-marking, quiet, 80 to 5,000 lb). Phenolic for high temp. TPR rubber for soft floors. Steel/iron for heaviest loads. Pneumatic for outdoor. No single "best" — match to application.
Per-wheel capacity ranges from 80 lb (small light-duty) up to 7,600 lb (large forged steel kingpinless). 4-wheel set covers loads from 320 lb to over 30,000 lb depending on wheel selection.
Polyurethane, TPR rubber, nylon, and most polyolefin are non-marking on tile, vinyl, and polished concrete. Hard rubber, steel, and cast iron can leave marks on light-colored floors.
This collection is replacement wheels only (the rolling part — tread + bearing + hub). For complete casters with wheel + swivel/rigid frame + stem already assembled, browse our complete caster collections.
Remove the axle bolt and lock nut from the existing caster, slide the worn wheel off, install the new wheel onto the axle, reinstall the bolt and lock nut. Total time: 60-90 seconds with the right tools.
Common bore sizes: 3/8 inch, 1/2 inch, 5/8 inch, 3/4 inch, 1 inch. Measure the existing axle diameter or check the existing caster's spec. Wrong bore = wheel won't fit on the axle.
Most wheels include roller bearings or precision ball bearings pre-installed. Sealed bearings available for wet/dirty environments. Bearing type affects rolling resistance and load handling.
Yes — in addition to standard materials, we stock blue solid polyurethane (premium), red poly on iron (heaviest), DuraTough poly on polyolefin (industrial), track wheels, and pneumatic outdoor wheels.
Yes — we stock matching replacement wheels for the major caster brands. If you have the existing caster's part number or specs, we can identify the right replacement wheel. Contact us with the existing caster's specs.
99 percent of caster wheel orders ship same or next business day from our Mansfield, TX facility via FedEx Ground. Bulk fleet orders over 100 wheels may ship freight. Cutoff 2pm Central.
Any wheel fits any frame when three specs match: diameter and width clear the frame opening, the bore matches the axle diameter, and the hub length fills the frame's inside width. Most industrial frames accept several tread materials at the same size, so you can change material at replacement time without changing frames.
Yes. Castor is the British spelling and caster is the US spelling of the same product. Specifications, sizes, and load ratings are identical. All castor wheel sizes listed by UK and EU manufacturers cross-reference directly to the US sizes in this collection.
