Mold-on-Rubber Dumpster Casters
Mold-on-rubber wheel casters for commercial dumpsters — quiet rolling, floor-friendly, and resistant to floor damage. The standard choice for indoor compactor receivers and dumpsters that roll across polished concrete or other finished surfaces.
What this page covers
Mold-on-rubber casters bond a rubber tread to a steel wheel core. The rubber absorbs noise and vibration during rolling, doesn't mark or damage finished floors, and provides better traction than steel or phenolic on smooth surfaces. The trade-off is wear life — mold-on-rubber wears faster than polyurethane or steel under heavy continuous loads.
PRT stocks mold-on-rubber casters in 6-inch and other standard wheel diameters, in load ratings appropriate 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 mold-on-rubber casters the right choice?
Indoor applications on finished floors (polished concrete, sealed tile, hospital and food-service environments where noise matters), and any application where standard casters scuff or damage flooring.
How long do mold-on-rubber casters last?
Typically 3-5 years in standard indoor service. Outdoor and continuous-load applications wear them faster — sometimes 1-2 years. For continuous outdoor service, polyurethane is a better choice.
Are PRT mold-on-rubber casters compatible with standard dumpster mounting?
Yes. PRT mold-on-rubber casters use standard NEMA mounting plate hole patterns and dimensions.
What is the load rating on a 6-inch mold-on-rubber caster?
Typical load ratings are 300-500 lbs per caster for standard configurations; heavy-duty options go up to 750 lbs. Match to your container loaded weight divided by 4 with a 25% safety margin.
