Description

6″ Gray Iron Wheel. Shown in photo is 6 x 3 with Roller Bearing.

Gray Iron industrial caster wheels are an affordable, reliable option for light-duty applications. These wheels feature a low initial cost and will not go flat, making them ideal for stationary loads or infrequent movement. Manufactured by Caster City, they include a lubrication fitting in the hub for easy maintenance. Available with roller bearings or sealed ball bearings, Gray Iron wheels come in 2” and 3” widths, with diameters ranging from 3” to 12”. They can handle temperatures up to 400°F, depending on the use case.

While strong and long-lasting, Gray Iron wheels are not suited for heavy-duty or abusive conditions due to their limited capacity and impact strength compared to Ductile Steel or Forged Steel wheels. They can damage most factory floors under heavy loads, so they are best used on steel plates, in channels, or as V-groove wheels on inverted angle iron tracks. For applications needing greater durability or floor protection, consider Ductile Steel, Forged Steel, or polyurethane wheels. Gray Iron wheels resist chemicals, won’t develop flat spots, and excel in stationary setups.

When are Gray Iron Wheels a good choice for heavy industry?

• Light-Duty Warehouse Carts: Moves small, lightweight items on smooth concrete floors.
• Stationary Machinery: Supports equipment that remains in place, preventing flat spots.
• Display Stands: Holds retail displays or exhibits on hardwood or tile.
• Heavy Duty Carts: Can roll with thousands of pounds of material

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.
