Caster Wheel Material Comparison
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.

How to Choose the Right Wheel
1. Calculate Per-Wheel Load
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.
2. Match Material to Floor Type
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.
3. Wheel Diameter for Threshold Clearance
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.
4. Hub Material Determines Maximum Capacity
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.

Frequently Asked Questions
What's the best caster wheel material?
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.
How much weight can a caster wheel hold?
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.
What wheel material is non-marking?
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.
Are these wheels only, or complete casters?
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.
How do I replace a caster wheel?
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.
What bore size should I order?
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.
What bearings come standard?
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.
Do you stock specialty wheel materials?
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.
Can I match wheels to my existing casters?
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.
How fast do wheels ship?
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.
