How to choose the right caster wheel material
Time：Dec 06,2024
To choose the appropriate caster wheels, you first need to select the right material for the single wheel. When choosing wheels, you should consider the size of the surface, obstacles, residual materials on the site you will be using (metal shavings? grease? or others?), the environmental conditions (high temperature, low temperature, or normal temperature), and the weight that the wheels can bear. The differences in cost and lifespan of casters made from different materials mainly reflect in the following aspects:
1. Polyurethane (PU): Polyurethane casters have excellent wear resistance, impact resistance, and oil resistance, making them suitable for various ground conditions, including rough and uneven surfaces. They are usually more expensive but have a relatively long lifespan and can maintain good performance in harsh environments.
2. Nylon: Nylon casters have excellent mechanical strength, chemical stability, and thermal stability. They are very wear-resistant and have good self-lubrication, making them suitable for use on smooth surfaces such as indoor floors and tiles. When used on rough surfaces, they may be subject to vibrations and impacts.
3. Rubber: Rubber casters have good shock absorption and noise reduction properties, protecting the floor from damage. They are suitable for places that require low noise and shock absorption, such as hospitals, laboratories, and office environments.
4. Cast Iron: Cast iron casters have extremely high wear resistance and load-bearing capacity, making them suitable for use in extremely heavy load environments. They are strong in impact resistance and high temperature resistance, suitable for heavy industrial equipment, steel mills, and heavy machinery that require extremely high load capacity. 5. Polypropylene (PP): Polypropylene casters are wear-resistant, impact-resistant, and have high chemical stability, with lower costs. They are suitable for medium load applications, such as light industry and food processing.
6. Synthetic Rubber: Casters made from this material have strong load-bearing capacity, suitable for various surfaces, rotate flexibly, produce low noise, and protect the floor. They have a long lifespan, especially in environments that require floor protection and low noise. 7. Pneumatic Wheels: Pneumatic wheels particularly protect the floor, absorb vibrations, and are suitable for light loads and soft, uneven surfaces.
When selecting casters, you also need to consider the load-bearing weight, usage environment (such as temperature, humidity, chemical corrosiveness), movement direction, and special requirements (such as noise reduction and shock absorption). For example, in low-temperature environments, the hardness and elasticity of polyurethane and nylon may change, and specially designed low-temperature casters may need to be selected. In high-temperature or chemically corrosive environments, materials that are heat-resistant or chemically resistant may need to be chosen. In summary, selecting the appropriate caster material requires a comprehensive consideration of the usage environment and the specific needs of the enterprise or business to ensure the durability of the casters and improve the efficiency of the enterprise.
