Advantages
- Superior Durability: TPU (wear resistance) outperforms traditional rubber and some plastics, ensuring a longer lifespan under frequent use.
- Chemical & Oil Resistance: Resists oils, solvents, and mild chemicals, ideal for industrial environments.
- Shock Absorption & Elasticity: High elasticity provides cushioning, reducing noise and protecting floors.
- Lightweight & Low Maintenance: Easier to clean (wipe with water) and lighter than metal-core wheels, enhancing portability.

Material & Structure
- TPU Material: Thermoplastic Polyurethane (TPU) offers exceptional abrasion resistance, high elasticity, and durability.
- Single-Axis Design: Simplified structure with one wheel axle, reducing weight and complexity while maintaining medium-duty load capacity (e.g., 80–150 kg per wheel).
- Bracket: Typically zinc-plated steel (2.3–3.0mm thickness) for corrosion resistance and stability.
-
Functional Specifications
- Sizes: Common diameters include 3-inch (75mm), 4-inch (100mm), and 5-inch (125mm).
- Mounting Options: Flat plate or threaded rod (e.g., M8–M12) for versatile installation.
