L10 life with respect to press fit
L10 life with respect to press fit
(OP)
do any one know how to take into consideration the pressfit issue when calculating L10 life. I have a situation where the pressfit of our bearings is causing negative clearance. i want to take into consideration this into my L10 life calculation.
I am thinkin of pressfit causing a radial force on the bearing, but how much is the funny question. may be there is no radial load present due to false pressfit, i do know the outerace / innerace may have dimples on em.

RE: L10 life with respect to press fit
to tell you the loss of life caused by
the preload condition of your bearing.
A lot depends on the rpm of the bearing
and if heat is a major factor. Preload
helps to equalize the forces on all of the
rolling elements but also imposes greater
loads on the bearing. The manufacture must
have an application engineer who should be
able to answer your questions.
RE: L10 life with respect to press fit
Since you have another post of a similar concern of L10 bearing life, apparently with a specific problem in mind a more detailed description of the problem/design would get a much better answer.
