Fast answer: Polyurethane wheels on industrial plate casters are the most reliable solution for warehouse carts on concrete floors.
Concrete Floor Realities
- Expansion joints cause shock loading
- Dust and debris increase rolling resistance
- Uneven slabs overload individual wheels
If floors are cracked or rough, increase wheel diameter first.
Best Wheel Materials for Warehouse Carts
| Material | Performance on Concrete | Notes |
|---|---|---|
| Polyurethane | Excellent | Best overall durability |
| Phenolic | Very Good | High capacity, dry floors only |
| Nylon | Good | Low rolling resistance |
| Rubber | Moderate | Shock absorption |
Load Calculation for Warehouse Carts
Always apply a safety factor when calculating per-caster load.
Recommended Mount Type
Most warehouse carts use plate mount casters.
