Features

• Wheel Material: Made of Polypropylene (PP). This material offers high abrasion resistance, high stain resistance, and good chemical resistance, making it durable in demanding environments . It is also known for being easy to maneuver manually and resistant to deformation under static loads .

• Bearing Type: Equipped with double ball bearings in both the wheel and the swivel head . This design significantly reduces friction for smoother rolling and swiveling, especially under heavy loads .

• Brake System: Features a "double brake" (total lock) mechanism. This single action typically locks both the wheel's rotation and the caster's swivel action simultaneously, ensuring the equipment is completely immobile when parked .

• Robust Construction: The bracket (fork and top plate) is typically made of pressed steel with a protective finish like zinc plating or electrophoresis to resist rust and corrosion . For a 4-inch model in this class, the load capacity can be substantial, often rated around 280 kg (approx. 617 lbs) per caster .

Functions

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

• Precise Positioning & Stability: The double brake system provides reliable locking, which is crucial for keeping machinery stationary during use, enhancing both safety and precision .

• Corrosion & Chemical Resistance: The PP wheel, combined with a treated steel frame, allows the caster to function in environments where it might be exposed to oils, greases, salts, water, and various chemicals without degrading .

• Low Maintenance Operation: The double ball bearings ensure efficient rolling, which can reduce the overall maintenance needs compared to plain bearing casters .

Ideal Applications

Given its heavy load capacity, robust PP material, and secure double brake, this caster is well-suited for:

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

• Warehousing & Logistics: Ideal for heavy-duty platform trucks, freight carts, and large containers that need to be moved and securely positioned in warehouses .

• Specialized Equipment: Suitable for use in environments with exposure to chemicals or moisture, such as in automotive workshops or food processing areas (depending on specific chemical resistance needs) .

• Institutional Applications: Can be used in hospitals, schools, or hotels for moving heavy service carts or equipment where stable locking is required .
