Heavy duty patent casters

Caster are an integral part of modern industry and everyday life. Whether it's on mobile equipment on the factory floor or in the shopping carts or luggage we use every day, wheels are an important part of the equation. The size of a wheel has a direct impact on its performance. The size of a wheel has a significant impact on its rolling resistance, its load-bearing capacity and its ability to adapt to different surfaces. As technology evolves, so do the demands on wheels. So, is a bigger size wheel always better? To answer this question, we need to take a closer look at the relationship between wheel size and various performance indicators.

According to one study, the size of a wheel directly affects its rolling resistance and load-bearing capacity. The study states that larger wheels typically have lower rolling resistance, which allows them to move objects more efficiently. In addition, larger wheels provide better stability on uneven ground. All of these factors make larger wheels perform well in certain application scenarios.

First. Effect of Wheel Size on Rolling Resistance

Rolling resistance refers to the friction encountered by the wheel in the rolling process, which directly affects the wheel's energy efficiency and movement efficiency. Smaller wheels encounter more friction when rolling due to a smaller contact area. Conversely, larger wheels, due to their larger contact area, can better distribute the pressure, thereby reducing rolling resistance. Studies have shown that an 8-inch diameter wheel has about 25% less rolling resistance than a 4-inch diameter wheel under the same conditions. This means that using larger wheels saves more energy and improves overall efficiency. For example, in the warehouse logistics industry, handling equipment often requires frequent movement of heavy loads. In such cases, the use of larger wheels can significantly reduce energy consumption and improve efficiency. According to a survey by the American Society of Mechanical Engineers, the use of large-size wheel handling equipment compared to small-size wheel equipment, energy consumption is reduced by about 20%, which not only improves productivity, but also reduces operating costs.

Second, the wheel size on the impact of load-bearing capacity

Wheel load capacity is another important performance indicator. Larger wheels usually have a stronger load-bearing capacity, because they can better distribute the weight. This makes larger wheels perform better in application scenarios where heavy loads need to be carried. Studies have found that wheels with a 12-inch diameter have about 50 percent more weight-bearing capacity than wheels with a 6-inch diameter. This means that the use of larger wheels ensures the stability and safety of the equipment in situations where heavy loads need to be carried. Take the example of a hospital bed in a hospital room, which needs to be moved frequently and often carries heavier patients. In this case, the use of large-size wheels can ensure the stability and safety of the bed in the process of moving. According to a statistic of the American Hospital Association, the use of large-size wheel beds compared to small-size wheel beds, the failure rate is reduced by about 30%, thus improving the comfort and safety of patients.

Third, the wheel size to adapt to the impact of different ground

Wheel size also affects its adaptability to different ground conditions. Larger wheels have better ground adaptation and provide better stability on uneven ground. This is due to the fact that larger wheels are able to spread the pressure better, thus reducing the bumpiness. Studies have shown that on rough ground, a 10-inch diameter wheel is about 40 percent more stable than a 5-inch diameter wheel. This means that in situations where you need to move through complex terrain, using larger wheels can ensure the stability and safety of your equipment. For example, in outdoor activities such as camping or hiking, backpacking carts carrying heavy loads need to move through a variety of complex terrains. In such cases, using larger wheels ensures that the backpacking cart remains stable and less bumpy on uneven ground. According to a user feedback survey conducted by Outdoor Activity Supply, backpacking carts with large-size wheels have about 25% higher user satisfaction compared to those with small-size wheels.

Conclusion
In summary, large-size wheels have obvious advantages in terms of reduced rolling resistance, improved load-bearing capacity and enhanced ground adaptability. Although large-size wheels may face some challenges in some specific situations, overall they perform better. For this reason, it is important to consider their size when selecting wheels. For application scenarios that require efficient, stable and safe mobility, larger wheels are definitely the better choice.
