The polyurethane coated wheel is made by wrapping a metal hub with polyurethane material. It has high hardness, strong load-bearing capacity, and its wear resistance is 3 to 5 times that of ordinary rubber wheels. It has good antistatic properties, which can effectively avoid electrostatic sparks. It performs stably in environments with acid, alkali, oil, etc., and has good elasticity, with excellent shock absorption and noise reduction effects. Widely used in logistics equipment, industrial manufacturing, warehousing, medical and other fields, it can be used as a load-bearing wheel and support wheel, and is a capable "assistant" for the operation of many mechanical equipment....
