A Concise Guide to Industrial Heavy-Duty Swivel Casters
In industry, "heavy-duty swivel casters" are mobility components specifically designed for large load equipment. The differences from ordinary casters mainly lie in materials, size, and structure, with the core goal being: to make heavy equipment easy to push and stable to stop.
1. Common Materials
- Nylon: Wear-resistant and quiet, suitable for clean or chemical environments.
- Cast Iron/Forged Steel: Impact-resistant, commonly used outdoors or in high-impact situations.
- Polyurethane: Leaves no marks on the floor, shock-absorbing, suitable for epoxy floors.
- Phenolic Resin: High temperature resistant, can operate continuously around 230 ℃.
2. Size and Load Capacity
The larger the wheel diameter, the easier it is to overcome obstacles, but it also takes up more space; the wider the wheel, the lower the unit pressure.
Standard sizes: 4, 5, 6, 8, 10, 12 inches (approximately 100–300 mm).
Extra heavy models: 16, 18 inches (400–450 mm), double wheel structure, single wheel set static load up to 12 tons.
3. Typical Applications
- Low center of gravity type: For scenarios requiring stability and low height such as machine tools and injection molding machines.
- Mini high load type: 2-inch wheel height but can support over 360 kg, suitable for space-limited equipment.
- Cold chain/clean room type: All stainless steel bracket, operates smoothly even at -40 ℃.
4. Selection and Customization
By providing parameters based on "load weight + floor conditions + usage environment," you can select the appropriate model. For special heights, brake types, or corrosion resistance levels, manufacturers generally can provide customized solutions within a week.
In summary: As long as the model is chosen correctly, equipment weighing several tons can be moved as easily as a handcart.
