Heavy Duty Casters fall into many different categories in the Caster and Wheel industry. There is usually an industry standard weight capacity range for casters and wheels to determine their weight classification. Anything over 1,250 lbs capacity per caster would be considered a Heavy Duty Caster. There are numerous categories that all fall into the Heavy Duty Caster category based on your weight capacity requirements. The weight capacities for heavy-duty casters can range from, 1,500 lbs, 3,000 lbs, 5,000 lbs, 10,000 lbs, 15,000 lbs, and 20,000+ lbs. Each capacity range is a different Caster Series that has different characteristics including sizes, wheel material options, heavy duty raceways with special ball bearings and larger mounting plate sizes. The heavier weight capacity you need for your caster the heavier duty the caster will be. When we start getting into heavier duty casters, many aspects of the manufacturing process change. For example, once you get into our Kingpinless 3 inch wide caster series the steel we use to manufacture these casters is much stronger in order for the casters to withstand the capacity and type of shocks typically seen in heavy duty caster environments. We use a Hot Forged ASTM 1045 Steel Design which eliminates problems associated with kinpin failure due to severe shock loading that commonly occurs with heavy duty caster applications. Our Top Plates and inner raceways are integrally forged construction and our raceway that contains the ball bearings in the swivel casters is precision machined, induction hardened, and sealed to provide an exceptionally smooth performance to reduce friction and wear and tear. Our ball bearings used in our heavy duty kingpinless swivel casters are 1/2" diameter HRC 45 Steel ball bearings which are made to absorb thrust and severe shock loads for industrial environments. We provide a 3/4" Axle with a zerk fitting in this series and top off the steel of the complete caster yokes with a zinc plated finish to add some extra resistance to rust while providing a beautiful looking caster at the same time.
The most common Caster Series we sell that would be considered a Heavy Duty Caster would start at our 1,500 lbs weight capacity range. This is a good caster series to consider when your total weight capacity for 4 casters needs no more than 6,000 lbs capacity. We consider this series our Medium to Heavy Duty Caster Series. The next size up would be our Kingpinless Caster series that has capacities up to 2,000 lbs per caster or 8,000 lbs for a set of 4 casters. Kingpinless Casters are always considered heavy duty casters due to their construction. Kingpinless Casters are manufactured to take more abuse than a standard Kingpin Caster by eliminating and upgrading parts that are known to weaken over time due to abusive caster applications.

To save money, many people prefer to order heavy duty replacement caster wheels instead of having to replace the entire Caster. If this is your case as well, head over to our large selection of heavy duty caster wheels and select the wheel material you need to replace.
