L10 Bearing Life Calculator
L10 Bearing Life Calculator
(OP)
Hi,
I have been given an Excel Spreadsheet which performs the L10 bearing life calculation for a series of different bearings that our company uses. The task is to change the spreadsheet so that it uses ISO data, and NOT the Timken data that it currently uses for the calculation. However, I'm having trouble understanding what some of the variables are referring to, such as 'Kt', 'Nc', 'Fg' (see attached screenshot). These are not present in the Timken catalogue, and I'm having trouble finding out what they mean. Could somebody please help?
Many Thanks.

This page found the definition of two of those variables.

Kt = relative thrust load factor - ball bearings
Nc - number of rotations of the ball and cage assembly
No Fg.
