CasterShoX; The Quiet Caster

Caster Concepts, Inc. announces the release of a noise reducing, shock absorption caster built on patented ultra-compact shock absorption technology, developed in part with funding from the National Institutes of Health.
In January 2007, Caster Concepts announced the release of a radically new line of shock absorption casters. After two years of research and development and a quarter million dollar investment, Caster Concepts is launching its line of CasterShoX casters. Based on patented ultra-compact shock absorption technologies, the CasterShoX shock absorption core is entirely contained within the caster wheel. As a result, implementing CasterShoX products is as simple as changing wheels. Tested in industrial settings, CasterShoX casters reduce noise sources by as much as 15 dbA, a magnitude of reduction providing significant effect in reducing noise induced hearing loss. As a result, the National Institutes of Health funded R&D for this product.
CasterShoX casters are identical to conventional casters in appearance, shape and size. CasterShoX caster wheels come in two standard sizes, 6x2 and 8x2. Wheels can be treaded with high quality Caster Concepts polyurethane ranging from 70A to 70D. Solid, high strength, glass-filled nylon wheels are also available. CasterShoX casters are available in single or dual wheel configuration. CasterShoX wheels use a giant, super smooth 6013ZZ deep groove ball bearing which guarantees superior roll-ability and ergonomic factors.
The CasterShoX core provides 3/4 of an inch of compliance and is currently manufactured with three varieties of spring stiffness. The light duty core has a 500 lbs capacity, the medium, 1000 lbs., and the heavy duty core, 1500 lbs. Compared to traditional spring loaded casters, CasterShoX casters are smaller, more economical and better performing because they inherently add damping to ensure stability.
