Spring Loaded casters are designed to absorb shocks and minimize the impact to the cart, resulting in smoother movement, reduced risk of damage and less noise. Spring loaded casters are ideal for applications where surfaces are not even or flooring has damage or debris. They are also great for applications where the load may be fragile or highly reactive to vibration, such as small parts or glass.
However, to achieve these benefits the spring loaded casters must have the right springs to achieve optimal spring deflection. There is a science to determining proper deflection, the wrong shock absorbing caster can actually do more harm than good. If the spring constant is too high, it could essentially be the same as not having a spring at all. If the spring constant is too low, it could extend the impact of the shock, and continue to vibrate excessively. Rest assured, our engineers are experts in the science of determining the right spring and caster combination for each individual application.
The high strength chrome vanadium springs provide longer life through constant flexing and compressing. The spring compression starts with as little as 25 pounds loading per caster resulting in cushioned loads and quiet empty returns. The long swivel lead reduces excessive shimmy and vibration while towing.
Shock absorbing casters are ideal for jet engine dollies, aircraft jacks, in-plant trailers, trash gondolas, lift truck stabilizer casters, revolving signs and parade floats.
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 track 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.
