CasterShoX® – Shock Absorption Casters With Unparalleled Noise Reduction

CasterShoX® Casters function similarly to conventional spring-loaded casters but have unique differences that make CasterShoX the superior choice. CasterShoX utilizes patented technology that combines the very best attributes of spring technology and polymer dampening technology that is unsurpassed in dampening the noise of a manufacturing environment while reducing shock load.

The bottom line is that the CasterShoX system can reduce shock loads by 80% and noise sources by 15 decibels. And because these wheels are available in standard sizes and fit in the same available space as the previous caster, retrofitting a cart is easy. Simply change out the previous caster and bolt on the new CasterShox version. It’s available in two standard sizes, 6×2 and 8×2, and fits into a 51 Series caster rig.


CasterShoX® casters have the ability to reduce workplace noise to levels that are safer for all employees. In addition, CasterShoX works great for transporting fragile components or products where repeated shocks may damage the components. CasterShoX also provides an added value for ergonomic situations.

Increases allowable exposure for workers

Hearing Loss is the 2nd most common illness suffered in the workplace. This is why the US Department of Labor has regulations about noise exposure through OSHA. The regulations state that 90 decibels dBa is the highest noise level an employee can be exposed to for 8 hours (a standard workday).  Every increase of 5 dBa reduces allowable exposure time in half.

To address these needs, the patented CasterShoX absorption system —  located in the center of a CasterShoX wheel — minimizes and even eliminates vibration that causes cart noise. The system also functions like shock absorbers on a vehicle, minimizing the impact on the cart and its contents.


Automotive and Aerospace plants, fulfillment centers, and any plant with a towline or manual cart will benefit from CasterShoX casters. CasterShox patented sound dampening technology is incorporated into a standard size caster which has proven to be the most cost-effective means to decrease cart noise without significant design changes or cost overruns.

Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.

Other options include threaded zerks for when an application is difficult and high level of maintenance is required and rack brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
