100mm Thermoplastic Rubber Caster Blue 4 Inch Castor Wheels Customized

4 Inch Thermoplastic Rubber (TPR) Blue Color Caster With Double Brake System For Industrial Equipment

Features

• Wheel Material: The wheel is made of blue Thermoplastic Rubber (TPR) . TPR is a high-elasticity material known for its shock-absorbing and noise-reducing properties . It is also non-marking and will not damage floor surfaces . The typical hardness is around 65 to 85 Shore A .

• Bearing Type: Equipped with double ball bearings in the swivel head (raceway) . This design provides excellent maneuverability and smooth swiveling under load, and ensures long-term durability .

• Brake System: Features a double brake system (total lock) . This single-action mechanism simultaneously locks both the wheel's rotation and the swivel movement of the caster, keeping the equipment completely stationary when parked .

• Durable Construction: The bracket (yoke and top plate) is typically made of heavy-gauge steelwith a protective finish, such as zinc plating, to resist rust and corrosion . Many models also include dust covers to prevent debris from entering the bearings .

• Load Capacity: For a 4-inch model, the load capacity varies by design but is substantial, typically ranging from 70 kg to 200 kg (approx. 150-440 lbs) per caster depending on the specific construction .

Functions

• Heavy-Duty Mobility: Facilitates the smooth and effortless movement of heavy industrial machinery and equipment, reducing physical strain during operation or repositioning .

• Secure Locking: The double brake system ensures the equipment remains completely immobile when parked, which is crucial for safety during loading/unloading or precise positioning .

• Quiet & Smooth Operation: The elastic TPR tread absorbs shocks and vibrations, ensuring quiet rolling and protecting delicate equipment from impacts .

• Floor Protection: The TPR material is non-marking and glides smoothly across floors without causing scratches or scuffs, making it safe for various floor types including tile, wood, and sealed concrete .

• Chemical & Moisture Resistance: TPR offers good resistance to water, detergents, acids, and many chemicals, making these casters suitable for washdown environments .

Ideal Applications

Given its combination of heavy load capacity, secure braking, floor-friendly tread, and chemical resistance, this caster is well-suited for:

• Industrial Manufacturing: Ideal for heavy machinery, assembly line equipment, tool trolleys, and mobile workstations in factories .

• Medical & Laboratory: Perfect for hospital beds, medical equipment, laboratory carts, and cleanroom equipment where quiet operation and secure locking are critical .

• Food Processing & Food Service: Suitable for food equipment, kitchen trolleys, and service carts due to its resistance to cleaning chemicals and water .

• Warehousing & Logistics: Great for heavy-duty platform trucks, freight carts, and industrial dollies in warehouses and distribution centers .

• Commercial & Institutional: Can be used on display racks, hospitality furniture, and institutional carts in hotels, schools, and retail environments .
