CasterHQ's 40 Series Casters are hot forged ASTM 1045 steel kingpinless casters that can withstand up to 2,000 lbs per yoke. Whether it's machinery, military, fabrication, tow-lines, or automotive equipment, the 40 series will deliver. Combined with our Red Ductile Iron Wheels also known as Ductile Iron Wheels which can stand up to 1,500 lbs per wheel, these wheels are economical for any application. Our semi-steel wheels are precisely machined with a tensile strength of 45,000 PSI and can withstand temperatures from -40F to 600F. Ductile Steel wheels come in different hub designs depending on the size of the wheel selected. Photos will match the hub design you order. If you have a special hub design such as a solid core, solid 3 spoke, solid 4 spoke, open 4 spoke, solid 5 spoke, 5 spokes, solid 6 spokes, or open 6 spokes, give us a call and we will let you know our inventory levels and the diameters available with your wheel design request.

Frequently Asked Questions

What is the load capacity of this caster?+

This 4" x 2" Red Ductile Iron Swivel 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.

What wheel does this caster use?+

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.

What plate size and bolt pattern does it use?+

This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 2-5/8" x 3-5/8" slotted to 3" x 3" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.

Is this a swivel or rigid caster, and how does the brake work?+

This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.

What temperature range can this caster handle?+

Rated for -40°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.).

What floors and applications is it best for?+

The Ductile Iron wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.

What is the overall mounted height?+

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.

How do I order, and what are the terms?+

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).
