FAQ

What is the yellow extra thick CPC industrial caster wheel designed for?
The yellow extra thick CPC industrial caster wheel was specifically designed for power towed applications and demanding tow line systems, where it handles the heavy demands of automated material handling equipment. It features a durable yellow polyurethane tire with a crown tread design that’s built to endure the intense abuse and wear that comes from hard tug work, making it ideal for tough industrial environments requiring superior ergonomic performance.

What sizes does the CPC caster wheel come in?
This caster wheel is 2″ wide and manufactured only in 8″ diameter. It includes extra-large precision sealed ball bearings (6204 PS) that are reduced using top hat spanners to fit a ½” axle, ensuring smooth operation and easy installation in compatible setups.

Does a polyurethane caster wheel roll easier than a rubber one?
Yes, under the same size load on a smooth floor, a polyurethane caster wheel rolls easier than a conventional rubber caster wheel. The CPC‘s crown tread design further enhances this by reducing contact area and rolling resistance, providing exceptional ergonomic performance that reduces draw bar pull in both powered and manual applications.

What’s the durometer of the CPC caster wheel and how is the tire made?
The CPC industrial caster wheel has an extra-thick polyurethane tire that’s chemically bonded to a sturdy aluminum center, with a durometer rating of Shore 85A. This construction ensures strong adhesion and reliable performance in demanding tow line applications, with a capacity of 2,000 lbs per wheel under ideal conditions.

How does the extra thick tire help with debris?
The soft, extra thick tire with crown tread design reduces rolling resistance when encountering debris or small objects on the floor. In practice, this extra thick and soft polyurethane tire allows the wheel to roll over such obstacles more easily while maintaining excellent maneuverability, improving mobility in less-than-perfect conditions.

Will the CPC wheel pick up metal shavings?
It’s largely untrue that a generic 95A polyurethane wheel is all you need to prevent metal shavings from FOD embedding into the tread surface. What really works well, particularly in high-risk areas like airport flightlines and tarmacs where rivets from fuselages are scattered on the ground, is this extra thick design. With a durometer of 85A, the extra resilience of the poly material combined with the increased tread thickness helps reduce the chance of metal shavings sticking in the wheel. In contrast, a harder 95A poly wheel tends to let shavings embed more easily, leading to premature tire failure.

Why are most 95A poly tires thin?
Most 95A poly tires are typically thin by design. This thinness helps them dissipate heat more effectively during use, and they also depend on their metallic cores to serve as a heat sink, drawing away and releasing built-up heat to prevent issues.

How does polyurethane handle heat in wheels?
Polyurethane is a poor conductor of heat, meaning it doesn’t transfer heat well. In wheels, this leads to heat buildup from friction during rolling and repeated usage; since it can’t dissipate the heat easily, it keeps accumulating until failure occurs (known as hysteresis). Ultimately, the polyurethane can liquify from the inside out, resulting in a catastrophic breakdown from ongoing heat accumulation.

What makes the CPC wheel different in handling impacts and shavings?
The CPC wheel stands out as an extremely thick and soft wheel with a crown tread design, featuring special additives in the polyurethane that enhance its ability to absorb impacts. The poly material offers extra resiliency and great impact resistance, meaning it flexes and essentially spits out metal shavings instead of letting them embed into the surface like they would on a hard, thin tire. The crown tread further enhances maneuverability and reduces stress during direction changes.

Where can I get the CPC caster wheel?
Caster City manufactures this industrial caster wheel in 8″ diameter, 2″ wide, complete with top hat spanners and 6204 PS precision sealed ball bearings for a ½” axle. This maintenance-free wheel does an outstanding job handling hard tug work in tow line applications. These are priced above average, but we can arrange an aggressive deal for you—it’s definitely a top choice for demanding powered material handling applications.

How are these caster wheels made?
These caster wheels are produced using liquid cast polyurethane directly onto aluminum centers, creating a seamless and robust bond for long-lasting performance in demanding tow line environments.

What are the tire properties of these wheels?
They come with non-marking yellow polyurethane tires with crown tread that roll easier than gray rubber wheels on smooth floors, with superior ergonomic performance that reduces operator effort. The crown shape provides better swiveling and direction changes, making them a practical upgrade for cleaner, more efficient movement in various settings.

What chemicals and applications can these wheels handle?
These wheels can withstand exposure to a wide range of chemicals and solvents. They’re suitable for industrial tow line applications as long as they avoid extreme conditions like shock, overloading, abuse, obstructions, poor floors, or prolonged storage under standing loads.

How does the CPC wheel provide cushion?
The extra thick, softer durometer (85A) CPC polyurethane on aluminum wheel with crown tread delivers more cushioning compared to thinner polyurethane wheels, offering better shock absorption, great impact resistance, and a smoother ride over uneven surfaces while maintaining excellent ergonomic performance.

What bearings does this wheel use?
This wheel is equipped with maintenance-free precision sealed ball bearings (6204 PS), which contribute to its smooth rolling and durability in heavy-duty tow line applications without requiring regular lubrication.
