ABSTRACT:
A rotary coupling for conducting high pressure liquid from a stationary source to a rotatable utilization device is disclosed. The coupling includes a hollow shaft, a mounting assembly having a cavity into which one end of the shaft extends and roller bearings for enabling rotation and preventing axial movement of the shaft, a packing surrounding the shaft in the cavity and resiliently compressed therearound, and a conduit for conducting high pressure fluid from the source to the cavity.
