Spherical Head

The spherical head is the portion of the thrust bearing bolt that perceives the hydraulic unit vertical load. In addition, it is also works to self-position the plate-shape bearing of the thrust bearing of the hydro generator. The spherical head, a common design element of a cylinder with end caps, is an area of the thrust bearing bolt that has an impact on the thrust bearing’s plate-shape bearing as well as the vertical hydraulic unit load.
