ISO 12168 is an International Standard that discusses plain bearings.
ISO 12168‑2 is the second part in the multi-series that lists, in graphic form, characteristic values used in the calculation of oil-lubricated plain bearings without drainage grooves.
ISO 12168‑2 on hydrostatic plain journal bearings is useful to:
The functioning of hydrostatic bearings is characterized by the fact that the supporting pressure of the bearing is generated by external lubrication. The special advantages of hydrostatic bearings are lack of wear, quiet running, wide useable speed range as well as high stiffness and damping capacity. These properties are also the reason for the special importance of hydrostatic bearing units in different fields of application such as machine tools.
The characteristic values are given in ISO 12168‑2 are necessary for the calculation of oil-lubricated hydrostatic plain journal bearings in accordance with ISO 12168‑1. They are based on the premises and boundary conditions laid out in the ISO 12168‑1. The diagrams can be used to determine the values needed for the computation.
When designing a plain bearing, the characteristic values listed in ISO 12168‑2 can be used for optimized bearings.
