Only manual applications requiring moderate speed movement are suitable for the Gold Key Equipment's Flat-free(Foam-filled) industrial casters. No air is present in the tires of foam-filled pneumatic wheels, which eliminates the risk of the wheels ever falling flat.
These sound-reducing, cargo-protecting, shock-absorbing casters also increase caster, spin, and bearing life. The more affordable option is our original, patented design with its distinctive "floating" axle underneath the springs. Users get the same traction as air-filled wheels to roll on the grass, dirt, and small pebbles.
