Polyurethane Caster Wheels with Iron Centers


Caster Barns Polyurethane is superior to rubber in resistance to grease, oil, cutting, chunking, and abrasive wear. These caster wheels can be used on almost any factory floor. As with moldon rubber, the bonding agent which holds the polyurethane tire ( tread ) to its iron center can be affected by exposure to some chemicals, impact, overloading, and the buildup of heat. Temperature range is -20° to 180° F. The principle benefit of a polyurethane wheel over the same size rubber wheel is increased capacity. Given the same size load on a smooth floor, a polyurethane caster wheel rolls easier than the same size conventional rubber caster wheel. However, when used at full capacity, polyurethane is not easy rolling. Given a manual operation under ideal conditions, polyurethane caster wheels have a safe operating capacity of up to three times the capacity of the same size rubber wheel. Capacity ratings are offered as an idea of what the wheel will carry without failure. They are not absolute, but rather depend on the usage and service.

Your conditions are almost never ideal, so select a caster wheel with much higher capacity than the weight you require. Polyurethane is not truly floor protective because it lacks the resilience and cushioning effect of soft rubber. However, polyurethane is less damaging to floors and cargo than "hard tread" wheels because it provides some tire deflection under load. Polyurethane caster wheels are not recommended for storage.

  • Polyurethane elastomer tread chemically bonded to cast iron core.
  • Offers higher weight capacities while providing good floor protection and quiet rolling operation.
  • Optional precision ball bearings and tapered roller bearings require less effort to start up and maintain a rolling load; they also generate less friction heat and may prolong the life of the wheel.
  • Works well in both indoor and outdoor environments; however cast iron core can rust; if this is an issue look at using aluminum or plastic core wheels.
  • Durometer: 95 Shore A (+/-5).
  • Temperature range: -40° F to 180° F.
