ABSTRACT:
Shaft seal packing which has a large number of thin annular packing members uprightly set onto, and closely fitted to, a shaft in axial layers by compressing them only axially with respect to each other in a stuffing box, the inner diameter of the annular packing members being almost the same as the diameter of shaft, so as to greatly increase the hydrodynamic resistance between shaft and packing member, and decrease the compression of packing members to shaft, at the same time.
