Gimbal Expansion Joints
Gimbal Expansion Joints are designed to absorb angular movements in multiple planes. They consist of two sets of hinges connected to a common gimbal ring, allowing for angular rotation in any direction. These joints are ideal for applications requiring flexibility in multiple directions, such as bridges and skyscraper buildings.

A Gimbal Expansion Joint is almost the same as the hinge type, except it can accept angular deflection in any plane. It contains two sets of hinge pins that are 90 degrees to the other. Each set of pins is attached to a gimbal ring in the center of the metal expansion joint. This type of metal bellows expansion joint eliminates axial force and pressure thrust as does the hinged type expansion joint. The two most common fitting combinations that Triad Bellows uses for gimbal expansion joints are flanges and beveled weld ends.
