Abstract

When an information provision program is implemented, an input screen is displayed on a display section (step 101). A specific designation number is input (step 103), and one or plural bearing performance indexes are selected (step 107). When bearing performance indexes are selected, bearing service conditions which are required depending on the bearing performance indexes are input. Then, performance calculation programs corresponding to selected bearing performances are activated (steps 110-1, 110-2, . . .), and obtained calculation results are simultaneously displayed.
