Main function 
Absorbs vibration and impact 
When the equipment moves on uneven surfaces, shock-absorbing casters effectively cushion impact forces from the ground, preventing vibrations from being transmitted to the equipment body. 
It is particularly suitable for vibration-sensitive equipment such as precision instruments, medical devices, and automated production lines. 
Protecting Equipment and Extending Its Lifespan 
Reduces loosening, wear, or damage to components caused by prolonged vibration, thereby extending equipment service life. 
Reduce noise and improve the work environment, particularly in offices, hospitals, laboratories, and other similar settings. 
Enhance mobile stability 
This ensures smoother and more stable operation of heavy-duty equipment during pushing, reduces operator effort, and prevents cargo from tipping over or shifting. 
Adapting to Complex Terrain 
It can maintain excellent traversability and stability on uneven, creviced, or slightly obstructed terrain.
