CUSTOMIZED SOLUTIONS
With the rapid development of industrial automation and logistics, industrial casters, as a crucial component of equipment and handling tools, play an indispensable role. However, the noise generated by industrial casters during use has become a major concern for many factory and warehouse managers. Noise not only affects the comfort of the working environment but can also adversely affect the health of operators and even reduce the lifespan of equipment. This article will delve into the causes, control methods, and solutions for industrial caster noise from multiple perspectives, helping companies select the right caster products and achieve an efficient and quiet production environment.
Industrial caster noise primarily stems from the caster's material and structural design. Common caster materials include polyurethane (PU), nylon, rubber, and steel. The elasticity and hardness of different materials directly affect the friction noise between the wheel and the floor.
Hard materials (such as steel wheels) tend to generate louder noise on hard surfaces, but they offer greater load-bearing capacity.
Elastic materials (such as polyurethane) offer excellent cushioning properties and can effectively reduce noise. The wheel hub design also affects noise. For example, a wheel hub with a shock-absorbing structure can absorb vibration and reduce noise transmission.
Comparison of Caster Performance of Different Materials
| Caster Material | Noise Level | Load Capacity | Wear Resistance | Applications |
| Polyurethane | Low | Medium-High | High | Office, Electronics, Medical |
| Rubber | Low | Medium | Medium | Medical, Food Processing |
| Nylon | Medium | High | High | Warehousing, Logistics, Heavy-Duty |
| Steel | High | Very High | Very High | Heavy Industry, Outdoor |
The floor's flatness, material, and cleanliness significantly impact caster noise. Rough or obstructed surfaces can cause additional vibration and clatter during caster operation. Furthermore, humid or oily environments can alter the coefficient of friction and may also affect noise levels.
The weight carried by the caster and its wheel diameter also determine noise levels. Excessive loads increase the contact pressure between the wheel and the ground, increasing friction noise. Casters with smaller wheel diameters experience greater vibration amplitude when encountering obstacles, producing more noticeable noise.
The noise generated by industrial casters not only affects employee comfort but can also cause hearing loss, distraction, and even cause equipment resonance, shortening equipment lifespan. Prolonged exposure to high-intensity noise can lead to occupational illnesses.
Caster noise is primarily measured using a sound level meter, measured in decibels (dB). Several international and domestic standards specify noise limits, such as:
| Standard Name | Scope of Application | Maximum Permissible Noise (dB) |
| ISO 11201 | Offices and Industrial Areas | 70 |
| GB/T 3785-2008 | Industrial Noise Measurement Standard | 75 |
| OSHA Standard | Workplace Safety Standard | 85 (8-hour weighted average) |
Scientifically evaluate caster noise characteristics through multi-point sampling, ambient noise elimination, and spectrum analysis. Analyzing the frequency distribution of caster noise helps identify the primary noise source and guide targeted noise reduction designs.
Polyurethane wheels: Due to their excellent elasticity and shock absorption properties, they are an ideal choice for noise reduction.
Composite wheels: Combining the advantages of multiple materials, they offer both load-bearing and quiet operation.
Wheel tread texture design: By varying the wheel tread texture, the contact pattern is optimized to reduce friction noise.
Bearing selection: Sealed high-precision bearings are used to reduce mechanical friction noise.
Elastic pads: Rubber or elastic pads are added between the wheel axle and the bracket to dampen vibration.
Multi-wheel combination design: Rationally distributes the load, reduces pressure on each wheel, and reduces vibration and noise.
Regularly check the wheel axle lubrication to ensure smooth rolling.
Clean the wheel tread and bearings to prevent foreign matter from causing noise.
Replace worn parts promptly to prevent increased noise.
