Bridgestone Hybrid air damper EZ type

Even in the vibration range of 20Hz or less, which has been difficult to achieve with anti-vibration measures with a single anti-vibration rubber until now, the anti-vibration effect has been greatly improved. Moreover, the amplitude generated at the time of resonance is suppressed low by the damping effect of the air that is provided with the orifice plate. Since the load is mainly supported by a metal spring, there is almost no creep that has been a problem with anti-vibration rubber, and the durability due to repeated amplitude is also at a high level. The change of the support spring due to temperature change is extremely small, and stable performance can be obtained over a wide temperature range. High attenuation is obtained by Bridgestone's original high damping rubber and air damping effect. Since there is no sliding part, it is excellent in maintainability, and an air supply source such as an air spring is unnecessary, so the total cost is greatly reduced.
