This 6-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.
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.
