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.

For heavy equipment, provide loaded mass, centre of gravity, castor layout and travel speed. Uneven load sharing or powered towing requires a specific review.

Prepare the enquiry

  1. Select the complete Code Number and confirm mounting dimensions and clearances.
  2. Describe load, floor, movement, temperature and cleaning conditions.
  3. 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.
