This document specifies the values of the basic functions used in the calculation procedure for oil-lubricated circular cylindrical hydrodynamic bearings under conditions of full lubrication.<\/p>\n

The values are given for the assumptions and boundary conditions given in ISO 7902-1<\/span><\/span>. The values necessary for the calculation can be determined from the tables of bearing characteristics, the graphs and from the formulae.<\/p>\n

The descriptions of the symbols used and calculation examples are given in ISO 7902-1<\/span><\/span>.<\/p>\n
