Not an air bearing like you are thinking, it is just a solid steel nose with several air holes drilled on the face of it which are connected to a compressed air source, this provides a cushion of air on the backside of the belt, the belt floats on the air cushion.air bearing... quite expensive .. how does the grit affect it, or is the grit too coarse to get into that fine cushion of air?
