Basin rubber bearing

Basin-type rubber supports utilize the elastic rubber blocks enclosed within a semi-closed steel basin, exhibiting fluid-like characteristics under tri-axial loading conditions to achieve

The rotation of the bridge upper section, simultaneously relying on the low friction coefficient between the PTFE sliding plates on the central steel plate and the stainless steel plate of the upper seat plate.

The horizontal displacement of the structure causes the shear force experienced by the support to no longer be solely borne by the rubber, but to indirectly act on the steel bottom bowl and the PTFE sliding plate in contact with the stainless steel.

Slippage between the gears.
