High-Strength Polyurethane PU On Steel Hub 4 Inch To 12 Inches Heavy Duty Industrial Caster Solid Pu Wheel-Plain Roller 65 Shore D

1. Material Composition & Construction
This wheel is engineered with a premium, high-strength polyurethane (PU) compound (65D hardness) that is solidly molded onto a robust steel hub. The integration of a ball-bearing core ensures smooth and durable rotation. This construction provides an inseparable bond between the tread and the hub, offering exceptional structural integrity and load-bearing capacity.

2. Key Performance Features

• Floor & Surface Protection: Non-marking and non-staining, ensuring excellent preservation of sensitive flooring.
• Operational Efficiency: Features low rolling resistance for reduced operator effort and low-noise operation for a quieter work environment.
• Exceptional Durability: Offers high resistance to abrasion, cuts, and tear propagation, resulting in a long service life even under heavy use.
• Chemical Resistance: Capable of withstanding exposure to a wide range of aggressive substances, including oils and solvents.

3. Technical Specifications

• Material: High-strength Polyurethane (PU) on Steel Hub
• Hardness: 65 Shore D
• Operating Temperature: -40°C to +80°C (temporarily up to +90°C)
• Note: Load capacity is reduced at ambient temperatures above +50°C.

4. Application Scenarios
This wheel is ideal for heavy-duty and industrial applications where durability, floor protection, and smooth operation are critical. Typical use cases include:

• Heavy-Duty Pallet Trucks & Hand Trucks: For demanding warehouse and logistics operations.
• Industrial Casters & Carts: On equipment used in manufacturing, assembly lines, and distribution centers.
• Food & Beverage Processing Plants: Where chemical resistance and easy cleaning are required.
• Cold Storage Facilities: Suitable for use in low-temperature environments down to -40°C.
