This 6-inch by 4-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.
Paired with our general-purpose, 1-inch thick tread, H.D. Standard Polyurethane (Shore 95A Hardness) wheel, this caster becomes good for numerous industrial applications. It is non-marking with high tear strength and resistance to flat spotting, as well as a good solvent and water resistance. This wheel is capable carrying loads up to 3700 lbs. and has a 1-inch thick tread which is denoted by the H.D. in the wheel material. 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 3000 lbs.
