Where it fits. Thermoplastic polyurethane is the general-purpose upgrade tread. It is non-marking, resists oils and most mild chemicals, and carries more load than rubber at the same diameter without the noise of a hard tread. TPU holds its shape under sustained static load, so carts parked loaded overnight are less prone to flat spots.
Construction. The tread is molded to a polypropylene core. Hub width is 1-13/16″. Thread guards are fitted to keep string, film, and debris out of the bore. A 5/16″ steel dual precision bearing fits a 5/16″ axle.
Load and duty. The 200 lb rating is per wheel. Standard practice is to size a four-wheel set assuming three wheels carry the load, so this wheel supports roughly a 600 lb cart with margin for shock loading and uneven floors. Continuous operating range is -15°F to 135°F.
About Series 20. Series 20 wheels cover our light and medium duty range, from 150 lb to 400 lb per wheel. The series includes the crown tread polyurethane family that has become a standard in retail, along with our high temperature wheels for bakery and food service equipment.
