3 characteristic values

See Figure 1 and Table 1 to 19.

This section gives a characteristic value used to calculate back to the oil tank is not lubricated radial sliding bearings are necessary, these values are based on

ISO 12168-1 specified premises and boundary conditions to use when calculating the value can be found from the chart, and explanation of symbols

Calculation example see ISO 12168-1. When designing a radial bearing, the characteristic values in Table 1 can be used to optimize the design of the bearing. […]
