CUSTOMIZED SOLUTIONS
Furniture casters, as essential components for furniture and equipment, not only affect the ease of movement but also directly impact safety, durability, and overall aesthetics. For caster suppliers and buyers, a thorough understanding of caster specifications and characteristics is crucial for selecting the right product. This article will provide a comprehensive overview of the key details and technical specifications to consider when selecting furniture casters, helping you make a professional and accurate purchasing decision.
Fixed Casters
Fixed casters have a fixed axle and can only roll in a straight line. They are suitable for furniture that requires linear or single-direction movement, such as tables and shelves.
Swivel Casters
The axle rotates 360 degrees, offering flexibility and convenience. They are suitable for furniture that requires multi-directional movement, such as office chairs and portable cabinets.
Locking Casters
Equipped with a braking system, these wheels can be locked to prevent furniture from moving when needed, making them ideal for applications requiring high safety.
Heavy Duty Casters
Designed to carry heavy furniture or industrial equipment, they offer a sturdy construction and high load-bearing capacity.
| Application Areas | Typical Furniture/Equipment | Recommended Caster Types |
| Home Furniture | Sofas, Coffee Tables, Storage Cabinets | Swivel Casters, Casters with Brakes |
| Office Furniture | Office Chairs, File Cabinets | Swivel Casters, Fixed Casters |
| Commercial Display Equipment | Display Racks, Mobile Shelves | Heavy-Duty Casters, Casters with Brakes |
| Medical Equipment | Mobile Beds, Instrument Tables | Heavy-Duty Casters, Non-Marking Casters |
| Industrial Equipment | Machine Trolleys, Toolboxes | Heavy-Duty Casters, Fixed Casters |
| Material Type | Characteristics | Advantages | Applicable Environments |
| Polyurethane (PU) | Highly elastic, wear-resistant, and silent | Suitable for floor protection, medium load-bearing capacity | Offices, homes, and medical facilities |
| Nylon | High hardness, wear-resistant and corrosion-resistant | Low friction coefficient, suitable for smooth floors | Industrial workshops and warehouses |
| Rubber | Soft, shock-absorbing, and non-slip | Good cushioning properties, silent | Suitable for various indoor and outdoor floorings |
| Cast Iron (C Iron) | Ultra-high load-bearing capacity, durable | Highly abrasion-resistant, suitable for heavy loads | Suitable for heavy industry and warehousing |
| Thermoplastic rubber (TPR) | Combining the advantages of rubber and plastic | Flexible, wear-resistant, and quiet | Suitable for medical and electronic equipment |
Wear Resistance: Harder materials such as nylon and cast iron are more wear-resistant, but can be more abrasive to the floor; softer wheels such as polyurethane (PU) and rubber provide better floor protection.
Quiet Performance: Rubber and TPR wheels are quieter and suitable for office and medical environments.
Load-bearing Capacity: Cast iron and nylon offer the highest load-bearing capacity and are suitable for heavy loads.
Chemical Resistance: Nylon and polyurethane (PU) are more resistant to common chemicals.
| Use Environment | Recommended Wheel Materials | Precautions |
| Indoor Hard Floors | PU, TPR | Protects the floor and prevents scratches |
| Carpet or Soft Floors | Rubber | Anti-slip, Excellent Shock Absorption |
| Heavy-Duty Industrial Environments | Cast Iron, Nylon | Strong Load-Bearing Capacity and Wear Resistance |
| Chemical Contact Environments | Nylon | Excellent Corrosion Resistance |
The load-bearing capacity of furniture casters is typically expressed as "maximum load per caster." When selecting, distribute the load appropriately based on the total weight of the furniture and the number of casters to avoid overloading that could damage the casters or tip the furniture.
Axle Material and Design: High-strength steel axles and dual-bearing designs improve caster load-bearing capacity and durability.
Hub Structure: Solid hubs are suitable for heavy loads, while hollow hubs are lightweight but have limited load capacity.
Mounting Base and Connection Method: A larger base provides more even load distribution; pole-mounted mounting offers a relatively low load capacity.
High-load casters often come with harder wheels, which may increase floor damage and noise. Therefore, when selecting light- to medium-load furniture, consider wheel materials with a balance of softness and hardness.
Appendix 1: Comparison of Key Technical Parameters of Furniture Casters
| Parameter | Description | Typical Value Range | Influencing Factors |
| Wheel Diameter | Wheel Diameter | 25-150 mm | Rolling Resistance, Load Capacity |
| Wheel Width | Wheel Width | 15-50 mm | Load Area, Stability |
| Maximum Load Capacity | Maximum Load per Caster (g) | 20-1000+ kg | Material, Structural Design |
| Mounting Method | Plate, Rod, Threaded Rod, etc. | - | Installation Ease and Stability |
| Swivel Angle | Fixed or 360-degree swivel | 0° or 360° | Mobility |
Plate Mounting
Advantages: Stable installation, suitable for flat surfaces.
Disadvantages: Requires pre-reserved screw holes for installation, making disassembly difficult.
Pole Mounting
Advantages: Easy and quick installation, commonly used for office chairs.
Disadvantages: Relatively low load capacity, limited applicability.
Threaded Rod Mounting
The threaded rod design provides a more secure installation and is suitable for furniture that requires assembly and disassembly.
Floor Type: For hard floors, carpets, tiles, etc., choose a wheel material and hardness that matches the floor to prevent scratches.
Ambient Temperature: For high or low temperature environments, use heat-resistant materials, such as high-temperature nylon.
Anti-Static and Explosion-Proof Requirements: Certain industrial environments require casters with anti-static or explosion-proof properties.
A larger wheel diameter reduces rolling resistance and is more suitable for uneven surfaces, but also requires more space and installation height.
Check that the wheels roll smoothly and without binding.
Check the bearings and shafts for looseness or wear.
Check that the brakes are functioning properly.
Regularly clean dust and debris from the wheel surface.
Apply lubricant to the bearings to reduce friction.
If cracks or deformation are found on the wheels, they should be replaced promptly.
For heavy-duty casters, regular bearing replacement is recommended.
Product Quality Assurance: Complete certifications and legitimate material sources.
Technical Support and Customization Capabilities: Whether technical consulting and customization services are available.
Pricing and Delivery Time: Reasonable pricing and on-time delivery.
After-sales Service: Comprehensive after-sales service and technical support.
