| Configuration | Code Number | Diameter (mm) | Catalogue load per wheel (kg) | Bearing |
|---|---|---|---|---|

Choose for the application
Compare polyurethane by tread construction, hardness and hub design, not colour alone. Different polyurethane formulations can behave differently under water, heat and repeated loading.
Prepare the enquiry
- Select the complete Code Number and confirm axle fit and hub dimensions.
- Describe load, floor, movement, temperature and cleaning conditions.
- Send quantity, destination country and any required drawing or inspection specification.
Practical checks
Pro tip: Supply the cleaning and temperature cycle with the enquiry.
Pro tip: Compare the code-specific hub, bearing and load rather than assuming every PU wheel is equivalent.
