Where it fits. Soft rubber is specified where quiet operation and floor protection outweigh capacity. The compliant tread absorbs shock and bridges floor seams, thresholds, and debris that would stop a harder wheel. Expect a lower load rating and more rolling effort than a hard tread of the same diameter.
Construction. The tread is molded to a polypropylene core. Hub width is 45mm. A 12-17mm steel single precision bearing fits a 12-17mm axle.
Load and duty. The 440 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 1,300 lb cart with margin for shock loading and uneven floors. Continuous operating range is -20°F to 140°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.
