Product Short Description 

Upgrade your heavy-duty equipment with our C01-R-1PU-650 casters. Featuring a premium 304 stainless steel fork and a 6-inch PU-on-Aluminum-Core wheel, this caster is engineered for extreme environments like seafood warehouses, docks, and coastal operations. With a massive 400kg loading capacity and optional brake, it ensures safety and durability where standard steel fails.

Key Features & Benefits 

• Superior Corrosion Resistance:​ Built with a 304 Stainless Steel bracket (5.5mm thickness), resistant to rust, salt spray, and chemical corrosion—ideal for harsh marine environments.

• High Load Capacity:​ Heavy-duty design supports up to 400kg per caster, perfect for large-scale industrial trolleys and machinery.

• PU on Aluminum Core:​ Combines the shock absorption and floor protection of Polyurethane (PU) with the lightweight strength of an aluminum core, preventing delamination and heat buildup.

• Precision Dimensions:​ Standard Top Plate (115x101mm) with Bolt Hole Spacing (84x71mm) and 11mm diameter holes for easy installation on concrete floors and heavy equipment.

• Customizable Solutions:​ We offer OEM/ODM services to customize wheel materials, temperature resistance ranges, and specific bearing types to meet your operational needs.

Detailed Product Description 

Built for the Toughest Environments

When operating in large seafood warehouses, coastal facilities, or busy dockyards, standard casters simply don't last. Our Heavy Duty 304 Stainless Steel Casters​ are specifically designed for these high-corrosion scenarios. We recommend directly choosing 304 Stainless Steel​ over ordinary carbon steel to avoid costly replacements and equipment downtime.

304 Stainless Steel vs. Ordinary Steel Plate

• Ordinary Carbon Steel:​ Prone to rusting, flaking, and structural failure when exposed to saltwater, humidity, or cleaning agents.

• 304 Stainless Steel (Our Standard):​ Contains chromium and nickel, offering excellent oxidation and corrosion resistance. It maintains its integrity and smooth swivel action even in wet, salty conditions, ensuring a longer service life and lower maintenance costs.

Advanced Wheel Technology: PU on Aluminum Core

The C01-R-1PU-650 features a 6-inch (150mm) PU wheel with an aluminum core.

• Why PU?​ Polyurethane offers high elasticity, wear resistance, and operates quietly without damaging sensitive flooring. It can be customized to withstand specific temperature ranges (e.g., low temps for cold storage or high temps for industrial ovens).

• Why Aluminum Core?​ Unlike cast iron cores that are heavy and prone to rust, the aluminum core provides exceptional strength while remaining lightweight, improving maneuverability and reducing the overall weight of your trolley.

Recommended Applications

• Seafood & Cold Storage:​ Perfect for trolleys in large seafood processing plants and refrigerated warehouses.

• Marine & Dock Operations:​ Ideal for port handling equipment, boat dollies, and coastal construction machinery.

• Medical & Laboratory Instruments:​ Suitable for sensitive equipment requiring non-corrosive, anti-static, or specific temperature-resistant casters.

• Heavy Industrial Trolleys:​ Concrete floor applications requiring high load capacity and reliability.
