A distance sensor configuration for a magnet of the levitation magnet of a magnetic levitation transport system equipped with a number of distance sensors. The present invention provides an aqueous fluoroelastomer curable composition comprising two liquids of a main material fluoroelastomer aqueous dispersion and a fluoroelastomer-curing agent aqueous solution, wherein the above main material fluoroelastomer aqueous dispersion is an aqueous dispersion having a pH of 6. A communicating passage comprising a groove or a hole is provided at the side of the bearing. The selected robotic mechanism is then controlled to perform the job request.
