PURPOSE: A hydraulic pressure damping bearing is provided to indicate the optimal progress of a dynamic flexibility factor and a spring constant in the high frequency area ranging from 150 Hz to 600 Hz. CONSTITUTION: The hydraulic pressure damping bearing has a spring element(6) acting between the first and the second fixed parts(2, 3), an acting chamber(10) filled with damping solution, and a pressure control chamber(11) connected to the acting chamber(10) with liquid being guided through a passage(14) separated from the acting chamber and bordered with a passage wall. When the first and second fixed parts(2,3) move relatively, the volume of the acting chamber(10) changes, so that the damping solution in the passage(14) is moved between the acting chamber(10) and the pressure control chamber(11). The acting chamber(10) and the pressure control chamber(11) are separated by a bulkhead(12) impacted by the damping solution. The bulkhead(12) is fixed to the second fixed part(3) through a separation body(13) consisting of two elements(31,32). The separation body elements(31,32) form a radial internal piece and a radial external piece(18).
