Shock Absorbing Casters by FOOT MASTER 

FOOT MASTER engineers invented the GDS Series in 1991, the world's first shock absorbing caster to utilize a special rubber cushion. It provides superior protection from mechanical shock and significantly reduces noise due to vibrations.
The GDS Series features a special NBR rubber rather than traditional coil springs. When subjected to shock load, this viscous material resists shearing motion and does not strain linearly with time. This eliminates shortened service life due to rust or loss of tension within standard metal springs.
Additionally, the NBR rubber offers a softer, more ergonomic ride with less recoil when the caster goes over obstacles. With multiple wheel and mounting options, the GDS Series has been the choice of professionals for a wide variety of applications. Visit us at www.footmastercasters.com to learn more.
