Polyurethane is the most-specified tread material for industrial casters — and for good reason. PU rolls quietly, applies low push-pull force on concrete and epoxy floors, and resists chunking under cyclic load. The "PU bonded to cast iron core" construction provides high capacity (up to 10,000 lbs per caster) with floor protection. Standard for warehouse and distribution-center applications across all 7 of our caster brands.

Common Applications
- General warehouse pick carts, tugger trains, dolly fleets
- Distribution-center order-picking equipment
- Light-to-heavy assembly tooling on epoxy floors
- Hospital and institutional carts (general-duty applications)
- Cleanroom and electronics manufacturing (with antistatic PU)
When to Choose Polyurethane Casters
- Floor is concrete, epoxy, or polished concrete (the dominant 95% of cases)
- Operating temperature stays below 200°F
- Quiet operation matters (PU is quieter than rubber, much quieter than steel)
- Floor protection is required (PU does not leave marks like steel or cast iron)
