This 12-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 our 1-inch thick tread, T/R 85A polyurethane wheel, this caster is a versatile solution that brings industrial-strength performance with a softer touch. This specialized formulation is engineered for easy and quiet rolling, making it an ideal choice for a wide range of applications. With its high tear and debris resistance, this wheel ensures exceptional durability and longevity. While offering moderate solvent and oil resistance, it is important to note its lack of water resistance and unsuitability for hot and humid environments due to the risk of microbial attack. 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 3800 lbs.
