BearingLab — rolling bearing life

Load a worked example

01Bearing type

02From the catalogue page

C dynamic [N]

C₀ static [N]

speed limit [rpm]

e threshold

X₀ static

Y₀ static

X, Y and e belong to the specific bearing series — read them off the page for the part you are considering. Below e the axial load does not count at all.

03Load and duty

F_r radial [N]

F_a axial [N]

speed n [rpm]

The load varies — use a duty cycle instead

04What you require

target life [h]

reliability

a_ISO

a_ISO covers lubrication and cleanliness and swings the answer more than anything else here. It is left at 1 because the tool cannot know your lubricant — see chapter 7.
