Spherical Bearing

Spherical bearings are structural components engineered for applications requiring significant rotational capacity. With a high-strength steel construction, these bearings are designed to handle substantial vertical, horizontal, and lateral loads, especially where large rotational displacements are essential.
​
How Spherical Bearings Work
Spherical bearings comprise a top steel plate, stainless steel and PTFE slides, a convex plate, curved PTFE, and a concave plate. The convex and concave plates slide against each other to facilitate the necessary structural rotations at beam ends. The stainless steel and PTFE slides minimize friction, allowing for smooth movement to handle expansion and contraction. Based on the bearing type—fixed, guided, or free-sliding—they can manage various forces and movements, including vertical loads, lateral forces, and longitudinal or transverse displacements. Guided bars and restraining rings within the bearing further support horizontal load transmission, making these bearings suitable for intricate bridge designs.
