Choosing the Right Kiln Car Wheels for Your Firing Process – Factors to Consider

When it comes to firing ceramics in a kiln, the selection of kiln car wheels is a critical decision. Kiln car wheels provide the necessary support, stability and mobility for kiln shelves and loaded kiln cars. Choosing the right wheels for your firing process is crucial for achieving optimal performance, safety and efficiency.

Let’s explore the key factors to consider when selecting kiln car wheels so that you can make an informed decision for your specific firing requirements.

Load Capacity

The load capacity of kiln cart wheels refers to the maximum weight they can support. You’ll need to consider the weight of your kiln shelves, stacked ceramics and kiln car when determining the appropriate load capacity.

It’s important to avoid overloading the wheels, as this can compromise their stability and lead to safety hazards. Make sure that the wheels you choose have a load capacity that exceeds the combined weight of your firing materials.

Temperature Resistance

Kiln firing involves high temperatures, which your kiln cart wheels will be exposed to. Therefore, selecting kiln car wheels with excellent temperature resistance should be a top priority.  Avoiding excessive undercar temperatures is critical for trouble-free operations.

High-quality wheels are typically made from durable materials like 1045 grade carbon steel, which can withstand the extreme heat generated during firing. The temperature rating of the grease used in the wheel bearings must not be exceeded.  Consider the maximum undercar temperature in your kiln and choose grease that can handle the specific temperature range.

Wheel Diameter and Width

The diameter and width of kiln car wheels impact the stability and maneuverability of the kiln car. Larger diameter wheels offer greater stability and weight distribution, reducing the risk of tipping or uneven loading.

Wider wheels, on the other hand, distribute the load more evenly, preventing excessive pressure on the kiln floor and prolonging the life of the wheels. Consider the dimensions of your kiln car and kiln shelves to ensure compatibility and optimal performance.

Maintenance and Longevity

Make sure that you understand the maintenance requirements of the kiln cart wheels you choose. Wheel Assemblies require periodic lubrication to maintain the bearings ability to provide smooth movement. Also consider the expected lifespan of the wheels and evaluate the cost-effectiveness of their maintenance and replacement. Investing in high-quality, durable wheels can save you time and money in the long run.
