PU (polyurethane) heavy-duty casters are known for their high load-bearing capacity, durability, and resistance to wear and tear. Here are some of the key features of PU heavy-duty casters:

  1. Load capacity: PU heavy-duty casters can typically support loads ranging from 500 lbs to over 4,000 lbs per caster.
  2. Durability: PU casters are designed to withstand heavy usage, impacts, and abrasion. They are often used in harsh environments, such as factories, warehouses, and construction sites.
  3. Smooth rolling: PU casters provide excellent rolling performance, making them easy to maneuver even under heavy loads.
  4. Non-marking: PU casters are typically non-marking, meaning they won’t leave scuff marks on floors or surfaces.
  5. Chemical resistance: PU casters are resistant to most chemicals, oils, and solvents, making them suitable for use in environments where these substances are present.
  6. Noise reduction: PU casters operate quietly and can help reduce noise pollution in the workplace.
  7. Corrosion resistance: PU casters are resistant to corrosion, making them suitable for use in wet or humid environments.


PU (polyurethane) heavy-duty casters are widely used in various industrial and commercial applications where heavy loads need to be transported. Some of the common applications of PU heavy-duty casters include:

  1. Material handling: PU casters are commonly used in material handling equipment, such as carts, dollies, and pallet jacks, to transport heavy loads in factories, warehouses, and distribution centers.
  2. Automotive industry: PU casters are used in automotive plants for transporting heavy auto parts and machinery.
  3. Construction: PU casters are used in construction equipment, such as scaffolding, cranes, and mobile platforms.
  4. Aerospace: PU casters are used in aircraft manufacturing and maintenance equipment, such as aircraft dollies and workstations.
  5. Healthcare: PU casters are used in medical equipment, such as hospital beds, stretchers, and carts.
  6. Food industry: PU casters are used in food processing and packaging equipment, where hygiene is important.
  7. Marine industry: PU casters are used in marine applications, such as boat trailers, marine dollies, and marine jacks.
