Gray Iron Caster Wheels from Caster City

The Gray Iron Industrial Caster Wheels we engineer at Caster City are a low-cost solution primarily chosen for their affordability, offering a budget-friendly option for applications where cost is a priority and floor protection is not a concern. Available in 2” and 3” widths with diameters ranging from 3” to 12”, these wheels are equipped with a lubrication fitting in the hub for easy maintenance and come with either roller bearings or sealed precision ball bearings for reliable performance. Designed to support heavy loads without developing flat spots, Gray Iron wheels are a practical choice for static or low-mobility applications in industrial settings, capable of withstanding temperatures up to 400°F depending on the application.

While Gray Iron Caster Wheels provide an economical alternative, they are not recommended for severe or abusive applications due to their lower strength compared to steel wheels. For only a modest increase in cost, we recommend our steel wheels, which offer nearly twice the strength and durability. Gray Iron wheels will damage most factory floors under heavy loads, so they are typically used on steel plating, in metal channels, or as V-grooved wheels rolling on inverted angle iron tracks to protect costly flooring. These wheels are best suited for environments where budget constraints outweigh the need for enhanced performance or floor preservation.

Ideal for cost-conscious applications requiring reliable load support, Gray Iron Industrial Caster Wheels deliver functionality at a low initial cost. However, for superior strength and longevity, we encourage customers to consider our steel wheel options.
