Caster material directly affects its wear resistance, load-bearing capacity, and service life. Primary materials for medium- and light-duty casters include polyurethane (PU), rubber, nylon, and steel.
Strong Wear Resistance: PU material is suitable for use on hard surfaces and resists wear.
Excellent Quiet Performance: Low rolling noise, suitable for environments such as offices and hospitals.
Chemical Resistance: Oil, acid, and alkali resistant, suitable for chemical and light industrial environments.
Excellent Shock Absorption: Absorbs impact from uneven surfaces and protects equipment.
Excellent Quiet Performance: Suitable for locations with strict noise control requirements.
Wide Application: Suitable for rough surfaces and outdoor environments.
High Load Capacity: Nylon casters have a higher load capacity than rubber casters.
Chemical Resistance: Suitable for use in chemical environments or workshops.
High Hardness: Rolls smoothly on hard surfaces, but has slightly lower shock absorption.
Extremely High Load Capacity: Suitable for heavy equipment or industrial assembly lines. Wear-resistant and durable: Long service life, but relatively noisy.
Table 1: Comparison of Common Medium- and Light-Duty Caster Material Performance
| Material | Load-Bearing Capacity | Wear Resistance | Shock Absorption | Quietness | Applicable Environment |
| Polyurethane (PU) | Medium | High | Medium | High | Indoor hard floors, offices |
| Rubber | Medium | Medium | High | High | Rough floors, outdoor |
| Nylon | High | High | Low | Medium | Factory workshops, chemical environments |
| Steel | Very high | Very high | Low | Low | Heavy equipment, industrial workshops |
Caster structure design is directly related to ease of use and safety. Common medium- and light-duty caster structures include rigid casters and swivel casters.
Stable linear rolling: Suitable for equipment requiring linear motion. High Load Capacity: Simple structure, with a load-bearing capacity superior to casters.
Easy Maintenance: Fewer wear parts, lowering routine maintenance costs.
High Flexibility: 360° rotation, suitable for tight spaces or locations with frequent turns.
Flexible Mobility: Easy to operate, improving work efficiency.
Slightly Lower Load Capacity: Compared to fixed casters, the load-bearing capacity is slightly lower, but sufficient for medium and light equipment.
Dual-Wheel Design: Distributes weight, resulting in smoother rolling and reduced ground pressure.
Single-Wheel Design: Suitable for smaller equipment or environments with limited space.
Table 2: Comparison of Medium- and Light-Duty Caster Structures
| Structure Type | Flexibility | Load Capacity | Applicable Scenarios | Maintenance Difficulty |
| Fixed Wheel | Low | High | Linear Moving Equipment | Low |
| Swivel Wheel | High | Medium | Office Furniture, Tool Carts | Medium |
| Single Wheel | Medium | Medium | Small Equipment | Low |
| Dual Wheel | Medium | High | Applications Requiring Smooth Rolling | Medium |
Load capacity is a key consideration when purchasing medium- and light-duty casters.
Static load: The weight the caster can support when the equipment is stationary.
Dynamic load: The actual weight the caster supports when the equipment is moving, which is usually slightly higher than the static load.
While this article does not provide a formula, it is recommended that when selecting casters, the load capacity of each wheel should be greater than 1/4 to 1/3 of the total weight of the equipment to ensure stability and safety.
For large equipment, it is recommended to use multiple casters for evenly distributed loads to reduce pressure on each wheel and extend caster life. Can be combined with dual or multi-wheel casters to improve overall load-bearing capacity.
Wheel diameter directly affects a caster's rolling smoothness, maneuverability, and shock absorption.
Suitable for lightweight equipment: Offers low load capacity and good maneuverability.
Suitable for flat surfaces: Offers smooth rolling, but has limited ability to navigate obstacles.
Ideal for light to medium-sized equipment: Offers a balance of load-bearing capacity and rolling flexibility.
Suitable for most industrial and office environments.
Excellent maneuverability: Easily navigates small obstacles.
Low rolling resistance: Suitable for long-distance movement or uneven surfaces.
Table 3: Wheel Diameter and Usage Recommendations
| Wheel Diameter Range | Load Capacity | Rolling Smoothness | Applicable Environment |
| 50-75mm | 50-150kg | High | Flat Floors, Small Equipment |
| 75-100mm | 100-250kg | Medium | Offices, Light Workshops |
| 100mm and Above | 200-400kg | High | Factory Workshops, Rough Floors |
Safety is a key consideration when using casters. Medium and light-duty casters typically feature a variety of brake designs:
Locks both the wheel and steering: Secures both the position and steering direction of the caster for enhanced safety.
Suitable for medical equipment or precision instruments.
One-Way Lock: Locks both the wheel and steering, suitable for office desks, tool carts, and other locations.
Easy to operate: Brakes with a single foot pedal.
Intelligent design: Automatically locks when the equipment stops, ensuring safe parking.
Reduces manual operation and improves work efficiency.
The long-term performance of casters depends on regular maintenance and proper use.
Remove debris and dust: Prevent the rollers from sticking.
Keep bearings lubricated: Extend rolling life.
Wheel Surface Wear: Excessive wear can affect load-bearing capacity and rolling smoothness.
Loose bearings: Tighten or replace promptly.
Floor Conditions: Avoid sharp objects and high temperatures.
Humidity and Chemicals: Rubber and nylon wheels are significantly affected, so choose a material based on the environment.
Avoid overloading casters.
Avoid sudden acceleration or stopping during movement.
Check the brake function regularly to ensure safety.
Medium- and light-duty casters play a vital role in equipment mobility in modern industry, logistics, and office settings. Proper selection of materials, construction, wheel diameter, and brake system, along with regular maintenance, can significantly improve equipment efficiency and safety.
