A liquid packing for shafts comprises a seal ring rotating at the machine speed, and a non-rotating seal ring which is tightly fitted to the housing and axially yielding. The rotating ring is made of a material of high thermal conductivity, high strength and surface hardness in the sealing area. The rotating ring carries one or more floating rings, with a sealing gap concentric with the shaft being formed therebetween. The rotating ring is made of a hardened copper beryllium alloy, the non-rotating ring of slide carbon.
