Polyurethane Dumpster Casters
Polyurethane wheel casters for commercial dumpsters in outdoor and mixed-use service — long-wearing, weather-resistant, floor-friendly. The best all-around choice for routes that include outdoor exposure.
What this page covers
Polyurethane casters bond a tough, abrasion-resistant polyurethane tread to a steel or aluminum wheel core. The result wears 3-5x longer than mold-on-rubber under continuous outdoor use, tolerates weather and pavement irregularities, and rolls quietly on most surfaces. It's the default choice for outdoor commercial dumpsters and indoor/outdoor mixed routes.
PRT stocks polyurethane casters in 6-inch and other sizes with load ratings for commercial dumpster service.
How to choose
Match by load rating, wheel diameter, mount type (bolt-on or weld-on), and caster type (swivel or rigid).
Send PRT a photo of your existing caster with the container model number and we'll confirm fitment.

Frequently asked questions
When are polyurethane casters the right choice?
Outdoor commercial dumpsters, mixed indoor/outdoor routes, and any application where you want longer wear life than mold-on-rubber. Polyurethane is the default upgrade from rubber for serious commercial service.
How long do polyurethane casters last vs. rubber?
3-5x longer in continuous outdoor service. Indoor service is similar to rubber in wear life.
Are polyurethane casters floor-friendly?
Yes — polyurethane doesn't mark or damage finished floors, similar to rubber. Steel and phenolic are harder on floors.
Do PRT polyurethane casters work in cold weather?
Yes. Standard polyurethane stays flexible to about -20°F. Specialty low-temperature polyurethane is available for sub-zero service.
