This 8-inch by 4-inch 80 series extra heavy duty caster, is meticulously engineered to withstand the most abusive applications. These casters are designed with heat-treated raceways to prevent brinelling and ensure long-lasting performance. The laser-cut formed legs provide additional strength, making them ideal for applications with side loading or skidding. Crafted with durability in mind, the yoke and top plate are manufactured through a drop forged process using C-1045 steel. The top plate features a machined raceway, while the threaded kingpin and 5-inch diameter machined yoke base raceway enhance stability. Components are heat treated to achieve a hardness of 40 + 2 Rc. The caster is equipped with a 1.25-inch precision tapered thrust bearing pressed over the kingpin, along with hardened ball bearings to complete the load-bearing raceway. With exceptional strength and reliable construction, the 80 Series Extra Heavy Duty Casters are the perfect choice for rugged industrial applications.
Combined with Forged Steel wheels, these casters become a powerhouse solution for heavy-duty industrial applications. These wheels are hot forged from high carbon steel billets, enhancing their grain structure, ductility, and tensile strength (64,000 psi). With precision machining, they meet tight tolerances, ensuring flat surfaces with rounded edges. Offering the greatest load capacity, impact strength, and rollability among caster wheels. With the proper wheels and bearings, these wheels are capable of withstanding temperatures up to 800 degrees. 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 5000 lbs.
