Structural Bearing Assemblies

Versiflex HLMR Pot Bearing Assemblies are suitable at locations where low-profile, high-load bearing devices are required. Versiflex HLMR Pot Bearing Assemblies are especially suited for curved or skewed bridges and other complex structures where the direction of rotation varies or cannot be precisely determined.

Uni – Directional Designs – PMG and PMCG Series

The addition of guide bars to the multi-directional bearing device allows for horizontal movements in a single direction and the capability to resist externally-applied horizontal forces in the orthogonal direction. Orientation of the guide bars in a direction parallel to the structural movement is critical.
The Center-Guided system consists of a single guide bar along the centerline of the bearing assembly. Center-Guided bearing devices are not recommended where the horizontal force exceeds 30 percent of the vertical force.
The Edge-Guided system utilizes two (2) guide bars which are external to the rectangular pot plate. An inverted pot assembly is typically detailed to economically provide uniform bearing along the guide bars.
Fixed bearing assemblies are designed to transmit horizontal forces in any direction through contact between the piston and the inside of the pot wall. Horizontal movement is restricted in all directions while accommodating rotational movement of the bridge superstructure.
The addition of PTFE and stainless steel sliding surface between the piston and the sole plate creates a bearing assembly that allows horizontal movement in any direction. A multi-directional bearing assembly does not resist externally-applied horizontal forces.
