Heavy Duty Industrial Casters and Listed Weight Capacities.

When you are searching for industrial casters for your heavy duty applications, you might observe that the weight capacity listed on the website or catalog may be different than the capacity you are discussing with a Caster Concepts solutions expert on the phone.

Both our catalog and website faithfully represent the maximum weight capacity for each Caster Series. However,  this capacity varies depending on the chosen wheel size and material based on your specific application requirements.

For instance, different wheel sizes and materials can alter a caster’s overall capacity. This becomes particularly significant when not all caster wheels are in contact with the ground simultaneously. Factors like uneven flooring, expansion cracks, or surface pitting can result in only three casters bearing the load at any given moment. And since three points make a plane, you have to add in a safety factor so that three casters can handle your total load capacity.

These plate casters offer reliable solutions to a variety of challenges involving heavier-load applications. They handle a range of 8,000 to 50,000 lbs. per caster and feature a swivel section for easier maneuverability. Depending on your load capacity and needs, you’re sure to find the right caster with these brutes. Here’s a quick overview:

90 Series Casters

90 Series Casters

90 Series Kingpin Caster. 8,000 lb. Capacity.

The 90 Series hardened precision machined raceways eliminate surface brinelling when the caster is subjected to shock loads. The 90 Series Kingpin Caster is ideal for power-drawn equipment, aircraft ground support equipment, trash gondolas, material delivery trailers, and towed trailers.

Highlight: This caster provides high load capacity at a good value.


91 Series Caster

91 Series Caster

91 Series Kingpinless Caster.  20,000 lbs. Capacity.

The 91 Series Caster has become a highly accepted industrial caster while evolving into a valuable investment for rugged applications by minimizing maintenance costs. It is valued for its simplicity and toughness for industrial applications where shock loading is prevalent. The ease of swiveling with the 91 Series Caster leads to very long lifecycles and many years of low-cost operation

This is a good industrial solution for power-drawn applications and automated guided vehicles, a variety of fiberglass mold, engine and paint line dollies, material carts, aircraft maintenance stands, production line delivery trailers, and much more.

Highlight: The swivel section construction puts the ball bearing in a sheer load, providing greater strength and smooth operation when swiveling in a loaded state

For abusive applications, we recommend a kingpinless caster. With this type of caster, you remove the failure point for the kingpin stretching. This is why a lower series like the 91 Series (kingpinless) has more weight capacity than the standard 95 Series (kingpin).

95 Series Caster

95 Series Caster

95 Series Kingpin Caster. 17,000 capacity, and 25,000 lbs. HD capacity.

The 95 Series Caster is ideal for high-load applications.  The integrally forged kingpin and slotted adjusting nut add strength and longevity to the swivel section.

Rugged applications include die carts, towed trailers, automotive plant equipment, aircraft maintenance stands, production line delivery trailers, paving machinery, and boat dollies.

Highlight: The 95 HD fits a gap between our 91 Series and our 99 Series with the ability to carry a load of 25,000 lb. With a high-capacity swivel section, the caster reduces force load, making it easier to move and maneuver

97 Series Caster

97 Series Caster

97 Series Kingpinless Casters.  10,000 lbs. capacity and 20,000 lbs. HD capacity.

The 97 Series features a maintenance-free swivel section with sealed precision ball bearings. We created it for a customer who needed a caster that could overcome the force needed to swivel without requiring a bigger drive system. The swivel section’s high hardness and precision machining tolerances allow for an even distribution of load, which lowers swiveling forces and prolongs battery life in constant movement applications.

Highlight: Our 97 Series casters easily maneuver around tight corners, reduce the drain on motor-powered platforms, and carry between 10,000 and 20,000 pounds per caster, respectively. They’re the newest muscle in motor-powered material handling

99 Series Caster

99 Series Caster

99 Series Kingpin Caster.  35,000 lbs. capacity and 50,000 HD capacity.

The 99 Series Extra Heavy Duty Caster is designed and built to carry the heaviest loads (50,000 lbs.) while delivering the longest cycle life and flawless performance. The yoke and top plates for this massive swivel section are manufactured by a drop forged process from C-1045 steel.

Optimal for die handling, marine, and automotive applications, the 99 Series also meets the needs for aerospace and aircraft ground support equipment.

Highlight: The 99 Series Caster is unsurpassed in the marketplace for quality and reliability. The dual raceway load design provides superior carrying capacity and the design assures smooth rotation of this massive caster even when heavily loaded.
