By　using　hysteretic　damping　resulting　from　superelastic　deformation　of　shape　memory　alloy　(SMA),　a　new　type　of　SMA-rubber　bearing　for　seismic　isolation　is　developed　in　this　paper.　A　mechanical　model　of　the　bearing　is　established.　Based　on　the　simulation　analysis　for　dynamic　responses　of　a　SDOF　isolation　system　applying　SMA-rubber　bearing,　the　dynamic　property　is　studied　in　detail.　The　results　show　that　the　SMA-rubber　bearing　has　excellent　performance　of　seismic　isolation　and　energy　dissipation.
