07 Series Alu Core Donut Orange PU Caster

07 Series –Alu Core Donut Orange PU Casters

High Load Capacity | Wear & Abrasion Resistance | Floor Protection | Chemical & Oil Resistance
Heavy Duty Industrial Caster | Chinese PU  Caster Supplier | OEM & ODM Available

Basic Information

• • Available Sizes: 4″, 5″, 6″, 8″

  • Load Capacity: 350KG – 450KG

  • This high-performance caster wheel combines a premium Polyurethane (PU) tread chemically bonded to a high-grade Aluminum alloy core. It is engineered for heavy-duty industrial environments that demand high load capacity, low rolling resistance, and superior floor protection. The rust-free aluminum core significantly reduces the wheel’s dead weight while maintaining maximum structural strength.

Key Features

1. High Load-to-Weight Ratio: The aluminum core offers exceptional structural strength comparable to cast iron but is significantly lighter, reducing user fatigue during manual transport.

2. 100% Rust-Proof & Corrosion-Resistant: Unlike iron cores, the aluminum core will not rust when exposed to moisture, making it ideal for humid or frequently cleaned environments.

3. Floor Protection & Silent Rolling: The elastic PU tread absorbs shocks and vibrations, rolling quietly without marking, scratching, or damaging warehouse or factory floors.

4. Ergonomic & Low Rolling Resistance: Precision ball bearings paired with a high-rebound PU compound ensure effortless start-up and smooth rolling even under maximum cargo loads.

Where to Use Our Casters

• Heavy-Duty Manufacturing & Assembly Lines: Maximum reliability for moving heavy machinery components, welding fixtures, and industrial workbenches, leveraging the lightweight yet high-strength aluminum core to significantly reduce manual pushing effort.

• Automotive Industry & AGV Automation: Perfect for continuous-duty tow-line carts, heavy parts racks, and AGVs (Automated Guided Vehicles); the low rolling resistance of our premium PU compound optimizes battery efficiency in 24/7 production plants.

• Modern Warehousing & Heavy Logistics: Ideal for high-capacity platform trucks, cargo pallet cages, and heavy stock carts, ensuring smooth, silent rolling and maximum floor protection on epoxy or concrete warehouse floors.

• Humid Environments & Cleanroom Applications: Excellent for food processing racks, chemical mixing carts, and pharmaceutical equipment, offering a 100% rust-proof, corrosion-resistant alternative to cast iron wheels during frequent washdowns.

• Aerospace & Precision Ground Support: Trusted mobility for transporting high-value aviation components and aircraft maintenance staging platforms, providing superior shock absorption and zero tracking/marking on critical hangar floors.
