A bearing pad support connection, comprising:
- a bearing pad support for supporting a bearing pad;
- wherein the bearing pad is connected to the bearing pad support by a pivot joint including a pivot pocket and a pivot,
- wherein the pivot includes a neck and a head, the head includes a rim with a wider dimension than the neck, and the head further includes a rounded outer surface at a longitudinal end,
- wherein the pivot pocket includes a sealing that abuts on the neck of the pivot of the pivot joint, wherein the pivot pocket includes an inner surface facing the outer surface of the pivot, and
- wherein the largest radius of the outer surface of the pivot is smaller than a radius of the inner surface of the pivot pocket facing the pivot.
A method to operate a bearing pad support connection, wherein the bearing pad support connection comprises a bearing pad support for supporting a bearing pad, wherein the bearing pad is connected to the bearing pad support by a pivot joint, wherein the pivot joint includes a pivot pocket and a pivot, wherein the pivot includes a neck and a head, the head includes a rim with a wider dimension than the neck, and the head further includes a rounded outer surface at a longitudinal end, wherein the pivot pocket includes a sealing that abuts on the neck of the pivot, wherein the pivot pocket includes an inner surface facing the outer surface of the pivot, and wherein the largest radius of the outer surface of the pivot is smaller than a radius of the inner surface of the pivot pocket facing the pivot,
- the method comprising the step of preloading the bearing pad support connection by applying a fluid pressure to a space between the pivot and the pivot pocket.
