The Gapmaster™ Aero-Caster® air bearing is specially developed for the smooth movement of loads over gaps and steps in the floor surface. Originally developed for theater applications to move stage sets and theater seating, the Gapmaster™ air bearing can also be effective in autoclave loading, moving dies over t-slots, moving loads into and out of elevators or onto flush-mount scales, lift tables, turntables and pit covers.

A perforated membrane encloses the Gapmaster™ air cushion and meters the rate of air flow. Upon encountering a gap, rapid outflow of air is prevented by the metering action of this membrane. Since the load is actually floating over the surface, the potential for floor damage is substantially reduced.
