3 Inch Red PU Iron Core Caster Wheel With Double Brake For Trolley And Equipment
Wheel Material: The tread is made of red Polyurethane (PU) , which is bonded to an iron core. This combination offers the floor-protecting, quiet-rolling benefits of PU with the high load capacity and durability of a metal hub .
Robust Core: The iron center core provides high strength and rigidity, preventing the wheel from deforming under heavy loads and ensuring long-term durability .
Brake System: Equipped with a double brake (total lock) mechanism, often activated by a side pedal . This single action locks both the wheel's rotation and the swivel movement of the caster.
Precision Bearings: Incorporates ball bearings for smooth and efficient rolling, reducing the effort required to move the equipment .
Durable Construction: The bracket is typically made of heavy-gauge steel with a protective finish, such as zinc plating, to resist rust and corrosion . For a 3-inch model, the load capacity is significant, often ranging from 150kg to 350kg (approx. 330-770 lbs) depending on the specific design .
Heavy-Duty Mobility: Facilitates the smooth movement of heavy trolleys, carts, and machinery, reducing physical strain during operation .
Secure Locking: The double brake system ensures the equipment remains completely stationary when parked, which is crucial for loading/unloading and safety .
Floor Protection & Quiet Operation: The PU tread is non-marking and absorbs shock and vibration, protecting delicate floors (like wood, tile, or sealed concrete) from damage and ensuring quiet operation.
Shock Absorption: PU material helps dampen vibrations from uneven floors, providing a smoother ride for sensitive equipment and reducing noise.
Given its combination of heavy load capacity, floor-friendly tread, and secure braking, this caster is well-suited for:
Material Handling & Logistics: Ideal for heavy-duty trolleys, platform carts, and freight dollies used in warehouses and distribution centers where quiet operation and floor protection are valued .
Industrial Equipment: Suitable for mounting on industrial machinery, tool cabinets, and workstations that require frequent repositioning but must remain stable during use .
Medical & Institutional: Perfect for hospital beds, medical equipment stands, and service carts in quiet environments like hospitals, hotels, and schools where noise reduction and floor protection are critical.
Retail & Display: Used on heavy retail displays, kiosks, and stocking carts that need to be moved smoothly across store floors without causing damage.
