8″ x 2″ Kingpinless Poly on Cast Iron Swivel Caster (41 Series)

A kingpinless polyurethane on cast-iron caster is a heavy-duty mobility solution designed for industrial applications that require both durability and smooth operation. The caster features a wheel with a polyurethane tread bonded to a cast-iron core, combining the benefits of both materials. The polyurethane tread offers excellent shock absorption, noise reduction, and resistance to abrasion, chemicals, and moisture. Meanwhile, the cast-iron core provides exceptional strength and stability, ensuring reliable performance under heavy loads and in rugged environments. The kingpinless design eliminates the need for a traditional kingpin, resulting in improved maneuverability, reduced maintenance, and increased durability. These casters are commonly used in manufacturing, warehousing, and distribution facilities, providing dependable mobility for machinery, carts, and equipment while maintaining stability and smooth operation.
