Product Description

Heavy Duty Trolley Wheel Caster Industrial Casters Wheels with Ball Bearing 

Key Features

1. Iron Core + PU Composite Structure for Double the Impact Resistance
The wheel core features a high-strength cast iron/steel core, providing ultimate rigidity and support, and preventing the deformation or cracking of the core that occurs in pure PU wheels under heavy loads. The outer layer is made of thickened polyurethane (PU), offering excellent elasticity, quiet operation, and floor protection.

2. Precise Coverage Across Multiple Sizes (4/5/6/8 Inches)
Available in four diameters: 4-inch, 5-inch, 6-inch, and 8-inch. The dynamic load capacity per wheel is 280 kg, 330 kg, 400 kg, and 420 kg, respectively. With four wheels, the total load capacity reaches up to 1.2 tons, easily handling the transport of heavy-duty molds, steel coils, and equipment.

3. Heavy-duty brackets, rock-solid stability
Brackets are stamped from ≥8mm thick steel plates with double reinforcing ribs at critical points, ensuring no deformation or breakage even under full-load impacts. The surface features eco-friendly galvanization, providing rust and corrosion resistance that withstands humidity, oil, and outdoor environments.

4. PU Tread: Quiet and Mark-Free, Protecting Expensive Flooring
Tested operating noise level ≤65dB , making workshop operations quieter. The PU material leaves no black marks and does not damage the floor, making it safe for use on epoxy, polyurethane, and tile surfaces, thereby saving companies on floor maintenance costs.

5. Low Rolling Resistance for Effortless Maneuvering Even Under Heavy Loads
Equipped with precision ball bearings, these wheels offer extremely low rolling resistance, reducing the starting force required by 40% compared to standard plain bearings. Even when carrying loads of hundreds of kilograms, a single worker can maneuver the cart with ease, significantly reducing physical strain.

Application

This industrial trolley caster wheel is engineered for demanding logistics and production settings:

Manufacturing Plants: Moving heavy dies, steel components, and assembly jigs on concrete floors.
Warehouse & Distribution: Heavy-duty platform trucks, roll cages, and tugger carts operating over expansion joints and uneven surfaces.
Automotive & Aerospace: Transporting tools and sub-assemblies without marking coated or sealed factory floors.
Cold Storage & Food Processing: The PU caster is resistant to moisture and many cleaning agents (stainless steel bracket variant available for wash-down areas).
