75mm PU Cast Iron Caster Wheels 3inch Cast Iron Roller Wheels

Red PU Iron Core 3 Inch With Double Brake Caster Wheel For Trolley

(1) Features

• High-Quality Material: The wheel is made of a durable Polyurethane (PU) tread bonded to an iron core. This combination provides the strength of metal with the flexibility of rubber.
• Superior Floor Protection: The red PU tread is non-marking and gentle on all floor types (including epoxy, tile, and wood), preventing scuffs and scratches.
• High Load Capacity: The robust iron core and heavy-duty steel bracket provide excellent impact resistance and the ability to support significant weight without deforming.
• Dual Locking System (Double Brake): Equipped with a double brake mechanism (usually a "face contact" or "total lock" brake) that simultaneously locks the wheel's rotation and the swivel movement of the top plate.
• Smooth Mobility: Precision ball bearings (often chrome steel) inside the hub ensure smooth rolling, low noise, and easy maneuverability even under heavy loads.
• Corrosion Resistance: The bracket typically features an electroplated or powder-coated finish to resist rust, oil, and chemicals, ensuring longevity in harsh environments.

(2) Functions

• Heavy-Duty Transportation: Facilitates the effortless movement of heavy machinery, equipment, and trolleys across workshops or warehouses.
• Directional Control (Swivel): The 360-degree swivel capability (usually with a double ball raceway for smooth turning) allows for precise steering and positioning of the cart.
• Secure Parking (Braking): The primary function of the double brake is to provide absolute stability. When engaged, it prevents the equipment from rolling or swiveling, which is crucial for safety during loading/unloading or when stationary on an incline.
• Shock Absorption & Noise Reduction: The elastic nature of the PU material dampens vibrations from rough floors and significantly reduces operational noise compared to all-metal or nylon wheels.

(3) Applications

Due to its strength, floor-friendly nature, and secure braking, this caster is widely used in:

• Industrial Manufacturing: Ideal for moving heavy machinery like presses, generators, and assembly line carts.
• Logistics & Warehousing: Used on heavy-duty platform trucks, roll containers, and warehouse ladders where secure locking is needed during rest.
• Medical & Healthcare: Suitable for hospital beds, heavy medical equipment stands, and operating tables where hygiene, silence, and stability are critical.
• Retail & Display: Used for heavy display racks or service carts that need to be moved during cleaning but locked in place during operation.
• Aerospace & Automotive: Frequently found under toolboxes, engine stands, and heavy maintenance equipment in hangars or garages.
