Industrial casters (also known as industrial wheels) are the critical core components that
enhance the mobility and durability of modern production equipment. In production
environments that demand high efficiency and stability, precisely matching load capacity
and wheel material is crucial.

This article will comprehensively introduce the two major industrial caster series—
the Light-Duty H22 & H35and the Heavy-Duty H40 Series—for different usage needs.
It will also deeply analyze the key features and suitable applications for NY Nylon Wheels and
PU Polyurethane Wheels, helping you make the optimal caster choice for your equipment.
I. Light-Duty Casters: H22 &H35 Series and Indoor Applications
Light-duty casters are specifically designed for lighter loads and indoor environments.
   1)H22 series
                                           

   2)H35 Series

                                      
Suitable Environments and Industries for Light-Duty Casters:
Beyond the most common applications in furniture, the H22 Series is widely used
in indoor areas where attention to detail and noise reduction are required:
   ◆Retail and Commercial Spaces: Mobile product display racks, lightweight
      promotional carts, allowing for frequent layout adjustments.
   ◆Office Environments: Office chairs, filing cabinets, projector carts,
      ensuring smooth mobility on wooden floors or carpets.
II. Heavy-Duty Casters: H40 Series and High-Load Outdoor Applications
The application of heavy-duty casters involves handling extremely high loads,
continuous long-distance movement, and outdoor industrial settings where stability
during movement is strictly required.
                                        
The H40 Series features an extremely sturdy exterior design, utilizing thick, structurally
reinforced steel plate housing, equipped with large-sized wheels and precision bearings.
Meet the transport needs of heavy-duty tooling trolleys in long-distance, high-load,
and high-speed environments.
Suitable Environments and Industries for Heavy-Duty Casters:
The H40 Series, and similar heavy industrial wheels, are the main force in
large indoor factories and warehousing/logistics systems:
    ◆Automotive Manufacturing: Used for heavy material and tool carts on
       automotive assembly lines.
    ◆Logistics and Warehousing: Outdoor large pallet and heavy cargo trolleys.
    ◆Mechanical Processing: Heavy-duty mold trolleys.
III. Caster Material Analysis
PU Wheel (Polyurethane) features
PU wheels (Polyurethane) are a preferred material due to their excellent elasticity
and wear resistance.
    ◆Load and Shock Absorption: Offers good shock-absorbing effects, reducing
       the impact of the equipment on hard indoor floors and providing a smoother
       experience for high-load, high-speed movement.
   ◆Durability and Floor Protection: PU wheels possess outstanding characteristics
      for wear resistance and tear resistance.
   ◆Noise: The cushioning properties of PU material make the noise generated
      during movement significantly lower than that of Nylon wheels, making them more suitable
      for indoor factories with strict requirements for a quiet working environment.  
NY Nylon Wheel features
NY Nylon wheels are high-strength casters commonly found in the light-duty series.
   ◆Load and Durability: Nylon material itself is extremely hard, featuring excellent
      high-load characteristics. It also shows superior performance in wear resistance,
      chemical resistance, and oil stain resistance, offering strong durability.
   ◆Noise: Due to their high hardness, NY Nylon wheels generate higher noise when
      rolling on hard indoor surfaces (such as concrete or ceramic tiles).
      Quiet environment needs should be considered.
