The盆式橡胶支座 utilizes an elastic rubber block enclosed within a semi-closed steel pelvic structure, exhibiting fluid-like properties under three-directional loading.

A point to facilitate the rotation of the upper part of the bridge, while relying on the low friction between the PTFE sliding plate on the middle steel plate and the stainless steel plate of the upper seat plate.

Coefficient of friction to achieve horizontal displacement of the upper structure, so that the shear force the support bears is no longer solely carried by the rubber, but indirectly acts

On the sliding between the steel bowl and the PTFE slide plate and stainless steel.
