This 21-inch by 6.90/9-inch 90 series caster, is a durable and high-performance solution designed to excel in demanding applications. Crafted through a drop forged process using C-1045 steel, the yoke and top plate of this caster exhibit exceptional strength and resilience. The integral forged kingpin seamlessly integrates with the top plate, while the precision-machined raceway and threaded kingpin ensure a secure assembly. Through rigorous heat treatment, all components are fortified for enhanced durability. The caster incorporates a precision tapered thrust bearing pressed over the kingpin, engaging the yoke for smooth operation, while hardened ball bearings complete the load-bearing raceway, providing reliable support for heavy loads. The precision-machined and hardened bearing raceways eliminate brinelling when subjected to shock loads, and a 1-1/4″ tapered thrust bearing ensures a precision fit. With its impressive load capacity and excellent value, the 90 Series Caster is a trusted choice for applications that demand durability, precision, and cost-effectiveness, delivering exceptional performance and long-lasting reliability.
