Rubber Expansion Joint

20GB, Gimble Expansion Joint

Gimbal type rubber expansion joints are designed to permit angular rotation in multiple planes. The arrangement consists of two pairs of hinge plates connected with pins to a common gimbal ring and attached to the expansion joints’ external or internal hardware. The gimbal assembly must be designed for the internal pressure thrust forces of the system. Gimbal type rubber expansion joints can be used in sets of two, or sets of two with a single hinge type joint to absorb lateral movement in multiple planes. They are commonly used when the support structure or adjacent equipment have load limitations.
