Types of Caster Wheels
1. Cast Iron Caster Wheels
Cast iron caster wheels are known for their exceptional durability and high load capacity, making them ideal for industrial applications. These wheels are abrasion resistant and can withstand extreme heat, providing longevity in demanding environments. They are commonly used in manufacturing and heavy-duty applications where reliability is paramount.
2. Flanged Caster Wheels
Flanged wheels are designed to operate effectively on steel tracking systems, minimizing guidance and rolling effort. The design helps reduce the toll on floors, making them suitable for applications where load capacities are high. Flanged wheels are typically made of cast iron or steel, ensuring strength and long wear.
3. Solid Caster Wheels
Solid wheels are unbreakable under typical service conditions and offer shock absorption, making them ideal for equipment that requires stability and durability. They can withstand high temperatures, which is beneficial in environments with varying heat levels. These wheels are often used in both industrial and general-purpose applications.
4. Ductile Steel Caster Wheels
Ductile steel wheels provide a balance of strength and cost-effectiveness, making them popular in manufacturing and warehousing settings. While they have a good load capacity, they may not match the performance of forged steel wheels but offer a practical solution for many applications.
5. Forged Steel Caster Wheels
Forged steel wheels boast superior load capacity and impact strength, making them suitable for heavy machinery and industrial use. Their design allows for better rollability, and they can handle greater stress compared to other wheel types.
6. Rubber Caster Wheels
Rubber wheels are commonly used in office furniture and hospital beds due to their quiet operation and floor protection features. They minimize noise and are ideal for environments where noise reduction is essential, such as in hospitals.
7. Polyurethane Caster Wheels
Polyurethane wheels are versatile and durable, making them suitable for retail environments and trolleys. They offer excellent resistance to chemicals and provide a smooth ride, making them a popular choice for various applications.
8. Nylon Caster Wheels
Nylon wheels are lightweight and non-marking, making them ideal for office chairs and lightweight carts. Their low load capacity makes them less suitable for heavy-duty applications, but they excel in environments where mobility and ease of movement are prioritized.
Applications of Caster Wheels
Caster wheels are utilized in a wide range of applications, including:
- Healthcare: Hospital beds and medical equipment require smooth mobility, making rubber and polyurethane wheels ideal for this sector.
- Manufacturing: Heavy machinery and carts benefit from the strength of cast iron and forged steel wheels.
- Retail: Trolleys and display units often use poly and rubber wheels for ease of movement and floor protection.
- Warehousing: Ductile steel and solid wheels are commonly used for heavy-duty carts to move goods efficiently.
- Office Environments: Nylon and rubber wheels are preferred for office furniture to reduce noise and protect floors.
