CG-MAX Green Poly on Aluminum Caster Wheels

May 05, 2026

Our premium CG-MAX green polyurethane on aluminum caster wheels are a top "go-to" choice for customers who want uncompromising performance. To understand why, it helps to look at what makes a caster roll well.

Good rolling performance and how to get it

There are a few different things that make a caster wheel roll better: wheel diameter, tread shape, bearing type, and good floor conditions.

• Wheel Diameter: Larger wheels reduce rolling resistance and make it easier to roll over debris, cracks and uneven surfaces.
• Tread Shape: A crowned (rounded) tread reduces the contact area with the floor, lowering friction and improving swivel and pivot performance.
• Bearing Type: Ball bearings provide the lowest rolling resistance compared to other options, resulting in smoother, more efficient movement.
• Floor Conditions: Matching the wheel to your floor is critical. Harder wheels perform best on smooth surfaces, while softer wheels excel on rough or uneven floors by conforming to imperfections.

How this applies to our poly on aluminum wheels

With these rules in mind, we can see how our CG-MAX casters measure up:

• Wheel Diameter: While available in smaller sizes, our popular 8" diameter wheel, the largest size, provides the easiest rolling experience.
• Tread Shape: The crowned (round) tread design provides reduced friction and improved maneuverability.
• Bearing Type: Equipped with a large, high-quality ball bearing, the wheels get smooth, low-resistance movement.
• Floor Conditions: This caster wheel excels on smooth floors commonly found in automotive facilities, industrial plants and warehouses. Its tread hardness is Shore A 95 (firm, but not too firm). It minimizes deformation under load, reducing the amount of contact with the floor to a minimum, improving push efficiency making it Ideal for smoother floors.

The CG-MAX polyurethane on aluminum caster wheel is engineered for maximum efficiency, durability and ergonomic performance in demanding applications. Its advanced polyurethane tread is both chemically and mechanically bonded to the aluminum core, providing superior adhesion and extended service life.

Unlike standard polyurethane wheels that rely solely on a mechanical bond, this dual-bond design significantly improves resistance to water exposure. The aluminum core provides excellent strength while reducing overall weight and offering rust resistance.

This caster wheel is rated for low-speed towing. For maximum strength, durability, capacity (size dependent) and extended service life, we recommend pairing it with a kingpinless caster rig, which further enhances overall longevity.

Final Thoughts

The CG Max polyurethane on aluminum wheel is a long-term investment built for durability and performance. In many applications, the cost of downtime and frequent replacements can quickly exceed the initial savings of lower-priced options. While the upfront cost is higher, it’s designed to outlast standard polyurethane wheels. Pairing this wheel with a kingpinless caster rig further enhances durability and service life of a complete caster.

Matching your caster to your environment is key to getting the best performance. The more you understand your conditions and limitations, the easier it is to choose the right solution. It’s important to note that polyurethane is not ideal for constant UV exposure, as prolonged sunlight can degrade the material quicker over time.
