Wa′ter-bear′ing.

A device in which water or steam pressure is employed to counterbalance the downward pressure upon a rotating shaft, thereby obviating friction.

Water-bearing.

In Shaw's (Fig 7089), water from a pump, or steam, is admitted through a pipe n communicating with an annular groove o in the plate d, supported by pillars c c resting on the bed-plate b. To the rotary shaft h is attached the disk g, having a circular groove near its edge for receiving the annular piston e, which bears upon the upper face of the plate d until the pressure exceeds a certain regulated amount; when this is exceeded, the disk g rises until the ring i surrounding the disk touches the upper inwardly projecting part of the piston, lifting it clear of the plate, and allowing the fluid to escape into the dome-shaped chamber k, whence it is drawn off by the pipe m.

See also palier glissant, Fig. 3496; hydraulic pivot. Described in Bramah's English patent, 1802.
