The selection of materials and performance analysis for industrial casters

Industrial casters refer to wheels used in industrial equipment, shelves, vehicles and other situations. The selection of materials and performance analysis have important effects on its service life, safety and stability.

I. Material Selection

1. Metal materials: Common metal materials include cast iron, steel, and aluminum alloys. Among them, cast iron casters have high strength and wear resistance, but are heavy; steel casters have high strength and wear resistance, but are prone to rust; aluminum alloy casters are lightweight, but have relatively low strength.
2. Plastic materials: Common plastic materials include polyurethane, polyamide, and polypropylene. Among them, polyurethane casters have high strength, wear resistance, and chemical corrosion resistance, but are expensive; polyamide casters have high strength and wear resistance, but are prone to aging; polypropylene casters are lightweight and inexpensive, but have relatively low strength.
3. Rubber materials: Common rubber materials include natural rubber and synthetic rubber. Among them, natural rubber casters have good elasticity and wear resistance, but are expensive; synthetic rubber casters are relatively inexpensive, but have poor elasticity and wear resistance.

II. Performance Analysis
1. Load capacity: The load capacity of casters refers to the maximum weight they can bear. Load capacity is related to material strength, structural design, and other factors.
2. Wear resistance: The wear resistance of casters refers to their ability to withstand friction and wear during use. Wear resistance is related to material hardness, surface treatment, and other factors.
3. Chemical corrosion resistance: Casters may come into contact with chemicals in some situations, so their chemical corrosion resistance is also an important indicator. Chemical corrosion resistance is related to material chemical stability, surface treatment, and other factors.
4. Noise and vibration: Casters may produce noise and vibration during operation, which is unacceptable for some situations. Therefore, the noise and vibration performance of casters also needs to be considered.
5. High temperature resistance: Casters may deform or soften in high temperature environments, so their high temperature resistance also needs to be considered.

In summary, the selection of materials and performance analysis for industrial casters need to consider multiple factors comprehensively to meet the needs of different situations.
