This listing is for a 4-inch diameter by a 2-inch tread width kingpinless Rigid Caster combined with a heavy-duty ductile iron wheel. Kingpinless Casters offer exceptional maneuverability and prevent kingpin failures commonly seen on standard casters due to severe shock loading. The caster is precision machined and induction hardened. The legs are double welded. The steel is made from ASTM 1045 Hot Forged Steel. Ductile Iron Wheels offer a 70,000 PSI tensile strength for heavy impact and shock load applications. These wheels should never be dropped on the floor as they are incredibly heavy-duty and can damage concrete. The swivels and Rigids both contain an 8MM thick steel construction which is thicker than any standard top plate caster of this size.
The product options on the right-hand side, such as the bearing type, shows an image of the type of bearing that will come pre-installed inside of the wheel and caster. This wheel comes standard with a 3/4" roller bearing and 1/2" spanner bushing if no option is selected. The roller bearing will roll easier than a bronze bearing, but bronze bearings are more resistant to corrosion, wear, and high temperatures. Bronze bearings are commonly used in many high-temperature applications, including powder coating.

This 4" x 2" Ductile Steel Rigid Kingpinless Caster – 1,500 lb is rated to 1500 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.
This caster runs a Ductile Iron wheel with a 2" tread width. Steel / iron wheels give maximum capacity and durability on smooth, hard industrial floors and tolerate heat.
This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 2-5/8" x 3-5/8" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.
This is a Rigid caster. Rigid casters track straight for directional stability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.
Rated for -45°F to 800°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).
The Ductile Iron wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.
The overall height (floor to top of plate or stem) is 5-5/8". Account for it when checking equipment clearance, dock height, and ergonomic working height.
We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
