Polyurethane Caster Wheels – Superior Performance Casters
- PY
- PYR
Polyurethane Caster Wheels from Caster City offer superior performance compared to rubber wheels, excelling in resistance to grease, oil, cutting, chunking, and abrasive wear. Available in green (PY) or red (PYR) polyurethane tread bonded to a durable iron core, these wheels are designed for versatility and can be used on nearly any factory floor. With a tire hardness of 90–95 Durometer (Shore A), they provide excellent durability while maintaining a temperature range of -20°F to 180°F. The bonding agent securing the polyurethane tread to the iron center may be affected by certain chemicals, high impact, overloading, or heat buildup, so proper application is key. Available in widths of 1.25”, 1.5”, 2”, and 3” and diameters up to 16”, these wheels support a variety of bearing types, including precision sealed ball bearings, roller bearings, or stainless steel bearings, ensuring smooth operation across diverse industrial settings.
The primary advantage of polyurethane wheels over rubber is their significantly higher load capacity – up to three times that of a comparable rubber wheel under ideal conditions on smooth floors. This makes them an excellent choice for heavy-duty applications in industries such as material handling, manufacturing, warehousing, and automotive, where they can be used on platform trucks, assembly line carts, or heavy equipment movers. While polyurethane wheels roll more easily than rubber at the same load, they may become less easy-rolling when pushed to their maximum capacity. Capacity ratings serve as a guideline for safe operation, but actual performance depends on usage, service conditions, and environmental factors. To ensure optimal performance, consult Caster City’s engineering team at 800-501-3808 for guidance on high-impact or high-temperature applications.
