12x4 Ductile Iron Rigid Caster

This 12-inch by 4-inch 90 series caster, is a durable and high-performance solution designed to excel in demanding applications. Through rigorous heat treatment, all components are fortified for enhanced durability. With its impressive load capacity and excellent value, the 90 Series fixed caster is a trusted choice for applications that demand durability, precision, and cost-effectiveness, delivering exceptional performance and long-lasting reliability. Paired with ductile iron wheels, they feature many of the same characteristics of cast iron however, ductile iron has higher tensile and yield strengths. Its greater strength and flexibility — and less brittle-like cast iron tendency — help ductile iron become a better alternative in shocking applications. Featuring our precision tapered bearings, the wheels are capable of absorbing excessive side thrust loading and can be used where high speed operation is essential, all with a load rating of 7500 lbs.
