The Inner Workings of the Ultra High Capacity Polymer Caster Wheels

Ultra High Capacity Polymer Caster Wheels from Caster City are engineered to support heavy loads while protecting floors from the damage typically caused by metal wheels. Unlike polyurethane wheels, which can develop flat spots or delaminate under prolonged static loads, these non-marking black polymer wheels are compression molded and machined for superior durability and performance. Their straight-sided design maximizes load capacity, making them an ideal choice for indoor applications on smooth surfaces where floor preservation is critical. Available in 2”, 3”, and 4” widths and diameters ranging from 3” to 12”, these wheels are equipped with 2 to 4 precision sealed ball bearings (depending on size) for smooth operation and long service life. With a hardness of 80 Shore D and a temperature range of -20°F to 250°F, they resist corrosion, chemicals, and impacts, offering a robust alternative to steel wheels.

These wheels are designed for a wide range of heavy-duty applications across industries, including material handling, manufacturing, warehousing, aerospace, automotive, and more. Their flat tread face ensures stable load distribution, and the compression molding process eliminates the risk of flat spots, making them perfect for equipment like platform trucks, assembly line carts, or automated guided vehicles (AGVs) that remain stationary under heavy loads. Capable of withstanding shocks, chemicals, oils, and acids, these wheels are also suitable for harsh environments like chemical plants, food processing facilities, or marine applications. For high-temperature settings (up to 250°F) or specialized needs, such as stainless steel bearings or roller bearings, Caster City offers customizable options to meet your requirements. For further assistance, contact our engineering team at 800-501-3808.
