Urethane roller coaster wheels are high-performance Vulkollan wheels commonly used in roller coasters and other ferris castor amusement rides to ensure a smooth, safe, and comfortable riding experience. Here's an analysis of these wheels based on material composition, common size specifications, and characteristics:

Material Composition

• Urethane: Urethane is a polymer with excellent wear resistance, elasticity, and impact resistance. It is a popular material for wheels due to its superior performance under various conditions.

• NDI (4,4'-Diphenylmethane Diisocyanate): NDI is a special isocyanate used in the synthesis of high-performance urethanes, enhancing the heat and chemical resistance of the wheels.

• PPDI (Polyphenylene Methylene Diisocyanate): PPDI is a polymeric isocyanate with high heat and chemical resistance, often used in the manufacture of high-performance urethane products.

• Vulkollan: This may refer to a brand name or a specific type of urethane material, known for its excellent wear resistance and tear strength.

Common Size Specifications:

• The size of urethane roller coaster wheels is typically customized based on the design and requirements of the roller coaster. Sizes may include diameter, width, and inner hole diameter, among others.

• Common sizes may range from 200mm to 1000mm in diameter, 50mm to 300mm in width, with inner hole diameters tailored to the specific axle size.
