The noise reduction effect of universal wheels is mainly affected by three factors: wheel body material, bearing type, and bracket structure. Corresponding optimization measures can be taken for different noise reduction needs. The material of the wheel body is the core: rubber wheels and PU wheels have good elasticity, low impact force when in contact with the ground, and the lowest noise (usually ≤ 50dB), suitable for noise sensitive scenarios such as offices, hospitals, and homes; Nylon wheels and cast iron wheels have high hardness and generate significant vibration and friction noise when in contact with the ground (usually ≥ 60dB), making them only suitable for industrial workshops and other scenarios with low noise requirements. In terms of bearing types, ball bearings (such as deep groove ball bearings) have low rotational resistance and noise levels 10-15 dB lower than sliding bearings, making them the preferred choice for silent design; If you need to further reduce noise, you can choose ball bearings with sealed covers to prevent dust from entering and reduce friction noise. The optimization of the bracket structure can also improve the noise reduction effect: using a stamped integrated bracket to reduce vibration at the joint of components; Add cushioning pads (such as rubber pads, PU pads) at the connection between the bracket and the wheel body to absorb the impact force during driving; The wheel surface is designed with honeycomb or anti slip patterns to reduce friction noise with the ground. In addition, keeping the ground clean during use and avoiding crushing stones and debris on the wheel surface can effectively reduce noise.

Common faults and troubleshooting solutions
During the use of universal wheels, it is easy to encounter problems such as rotational lag, increased noise, rapid wear on the wheel surface, and brake failure. Timely troubleshooting and resolution can prevent the expansion of the problem and ensure safe use.
The core misconceptions and correct methods of selection
Many users are prone to falling into the trap of "only looking at the price" and "ignoring the scenario" when choosing universal wheels. The correct selection should follow the logic of "setting requirements first, then selecting parameters" to avoid poor user experience or safety hazards caused by improper selection.
