Series　of　test　on　a　new　type　of　seismic　isolation　bearing　are　introduced　in　the　paper.　The　new　bearing　is　combined　with　Teflon　sliding　system　and　helical　springs.　The　function　for　seismic　isolation　of　the　bearing　is　ensured　by　the　sliding　interface　between　the　disc　of　Teflon　and　the　stainless　steel　plate,　while　the　restoring　force　is　provided　by　springs.　During　the　experiment,　the　frictional　coefficients　between　Teflon　sheet　and　steel　plate　were　tested,　and　the　hysteretic　loops　of　the　bearing　excited　by　the　sinusoidal　and　record　earthquake　waves　were　tested　as　well.　In　addition,　the　test　of　the　hysteretic　properties　of　the　bearing　under　the　dynamic　pressures　were　carried　out.　It　is　shown　that　the　sliding　velocity,　vertical　pressure　and　types　of　seismic　excitation　have　important　effects　on　the　frictional　coefficients　and　hysteretic　characteristics.
