Spring Loaded Casters

A cart moves more smoothly, there is less chance of damage, and there is less noise when using spring loaded casters because they are made to absorb shocks and lessen the impact to the cart. For applications where there are uneven floors, damaged, or debris-filled flooring, spring loaded casters are perfect. They work well in applications where the load, such as small parts or glass, may be delicate or extremely sensitive to vibration.

The correct springs must be used in the spring-loaded casters to obtain the best spring deflection, though, in order to reap these benefits. Determining the right deflection requires science; using the improper shock-absorbing caster can have the opposite effect of what is intended. It can be equivalent to not having a spring at all if the spring constant is set too high. If the spring constant is too low, the shock’s impact may be prolonged and the device may continue to vibrate too much. You can be sure that our engineers have mastered the art of selecting the ideal spring and caster combination for each unique application.

Overview
The continual flexing and compression of the high strength chrome vanadium springs extends their lifespan. With as little as 25 pounds of weight per caster, the spring compression begins, producing cushioned loads and silent empty returns. While towing, the lengthy swivel lead lessens excessive shimmy and vibration.

Application
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.

Options
There are several different caster alternatives available. Many of these not only increase functionality but also increase safety and product longevity. The most frequently taken into account safety features include reinforced legs, toe guards, caster locks, and caster brakes. Options that seal a caster’s bearing and prevent contamination of the precise parts are the main options for extending caster life.

Other choices are rack brush wipers, which prevent debris from impeding motion or harming a wheel, and threaded zerks, which are used when a difficult application and high level of maintenance are needed. These options can be included either during the production process or after the caster has been entirely put together.
