This paper presents tension performance and shearing performance under tensile force of high damping rubber bearings. Two full-scale high damping rubber bearings, which are same in scale and performance, are tested. Simple tension and compression tests are carried out on one of two specimens. Shearing tests under tensile force are carried out on another specimen. Following conclusions are obtained by these experimental works. 1)In a simple tension test, bending deflection takes place on plane of rubber bearing flange plate. Axial strain of outer part of rubber bearing became large by bending deflection of flange plate. 2)If the tensile deformation of a rubber bearing is restrained less than tensile yield, shearing performance under tensile force is scarcely affected by tensile force. 3)If a rubber bearing strained tensile deformation exceeding yield and over 200% shearing deformation angle at the same time, hardening of rubber affects shearing restoring force.
