CasterHQ's 4 inch diameter by 2 inch wide Red Ductile Steel Wheels are made out of Ductile Iron, extra thick walled, heavy-duty core hub and tread. These wheels have a 45,000 PSI rating and can withstand up to 800 degrees Fahrenheit. Ductile Steel Wheels have a high ductility tensile strength meaning these wheels can absorb shock and impact without shattering like most steel wheels. These steel wheels are great for applications that require a high weight capacity with strict safety standards. Ductile Steel wheels are ideal for Heavy Duty applications where a standard polyurethane tread wheel cannot handle the weight of the application. Steel wheels can cause uneven concrete to chip or further degrade if you are rolling these over obstacles or gaps in the floors. If you have a smooth concrete floor these wheels should be fine as long as they are not being dropped onto the floor. These wheels can withstand up to 800 degrees Fahrenheit but the standard roller bearings can start to become brittle and eventually fail and you will need to replace the bearings if they are used frequently over 400 degrees F. This type of wheel is commonly used in high heat applications including powder coating due to its strength and durability.

Frequently Asked Questions

What is the load capacity of this caster?+

This 4" x 2" Ductile Steel Swivel 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 4-1/2" x 6-1/4" plate and a 2-7/16" x 4-15/16" slotted to 3-3/8" x 5-1/4" 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 -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.).

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).
