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.
Applications & Venues
Logistics & Warehousing: Medium-duty trolleys, picking carts, and conveyor systems in distribution centers.
Medical Equipment: Hospital carts, mobile workstations, and lab tools where quiet, non-marking movement is critical.
Furniture & Commercial Use: Office chairs, display racks, and service carts in retail/hospitality sectors.
Industrial Machinery: Assembly line equipment and packaging stations requiring oil-resistant wheels.
