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 an aluminum core. Hub width is 2-1/2″. A 1/2″ steel dual precision bearing fits a 1/2″ axle.
Load and duty. The 700 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 2,100 lb cart with margin for shock loading and uneven floors. Continuous operating range is -30°F to 140°F.
About Series 50. Series 50 wheels are our heavy duty line, designed for challenging environments and loads up to 5,000 lb, engineered for high shock and impact, maximum capacity at minimal height, and floor protection under load.
