Exploring the Science Behind Shock-Reducing Casters

Technological innovation is a critical element of scientific and technological advancement. It drives discoveries, enables research breakthroughs, and helps us live more efficient, convenient lives.

Trash gondolas often move over uneven surfaces, resulting in rattling noise and vibration. Using shock-reducing casters can significantly reduce this issue and protect the load from impact damage.


Shock reducing casters have unique springs that deflect when pressure is applied. These springs help cushion and dampen the shock and vibration caused by uneven surfaces or rough terrain while transporting heavy loads. The caster manufacturer’s applications engineers can help configure the spring deflection for your specific application. Exceeding the caster’s rated capacity could damage the springs, resulting in no shock-absorbing effect.

Shock-reducing casters also help reduce noise levels in manufacturing environments. Trash gondolas are standard in many industrial environments, and when moved over uneven surfaces, they create rattling noise that can disrupt the work environment. Noise-reducing casters help decrease noise, allowing for more focus on work tasks.

Shock-reducing casters are designed to reduce the impact of side, top, and bottom movements on carts during transportation. These casters also dampen vibrations and noise, resulting in less damage to equipment and materials during transport and improving workplace safety.

The design of these casters uses a piston to compress and decompress hydraulic fluid, creating a dampening effect on the wheels. The casters also feature a pre-load that establishes the initial force applied to the spring. This initial force determines how much the casters absorb during movement and how quiet they will operate.

Technology innovation brings about significant advancements in a wide range of fields. It drives progress in healthcare, communication, transportation, and education. 


Technology innovation plays a vital role in addressing societal challenges. It drives solutions to healthcare access, poverty alleviation, environmental sustainability, and disaster management.

Like all equipment, casters aren’t invincible and are susceptible to damage from repeated stressors. Sudden forces or misuse can result in immediate structural damage, such as bent mounting plates or cracked wheels. Constant exposure to abrupt forces can also reduce a caster’s lifespan, meaning it will require replacement more frequently than expected.

Shock-reducing casters help prevent damage to sensitive payloads and enhance workplace safety. They’re commonly used on carts and equipment in automotive manufacturing environments to minimize impact and reduce noise levels, ensuring precision tools and auto parts are protected during transportation. Likewise, it can protect hospital equipment from jarring vibration and movement and reduce the noise that disturbs patients during their stay. It helps keep them comfortable and focused on their recovery.

When used on carts, dollies, gondolas, or other wheeled devices, shock-absorbing caster wheels minimize the high noise levels generated by these material handling products. They also reduce vibration and jolting, protecting the contents of carts from damage and eliminating jarring for employees moving equipment in manufacturing facilities or warehouses.

Unlike standard casters, shock-reducing casters flex and compress when rolling over rough surfaces or floors. It reduces impact energy, dampens jarring, and helps to extend wheel, axle, and bearing life, lowering maintenance costs.

However, like all equipment, shock-reducing casters aren’t invincible. Abrupt and excessive forces can impose immediate structural damage on them, shortening their lifespans. Continuous exposure to shock loading and misuse can lead to wear and tear, shortening lifespan. Casters should be loaded within their rated capacity to ensure maximum performance and longevity. Using them beyond this could damage the springs, rendering them useless and creating excessive vibration.
