We have now said how to select bearings based on the fundamental extra dynamic load; when using rolling bearings at high temperatures; the bearing hardness decreases; the fatigue life is reduced compared to the normal temperature. Therefore, the fundamental additional dynamic load should be estimated to be smaller. Make a change.
Ct=ft0é¸†:
Ct: the fundamental extra dynamic load (N) modified according to the operating temperature; (kgf)
Ft: temperature coefficient; (125 degrees; coefficient is 1,150 degrees; coefficient is 1,175 degrees; coefficient is 0.95,200 degrees; coefficient is 0. 90,250 degrees; coefficient is 0.75)
C: fundamental extra dynamic load (N); (kgf)
Pay attention to; when using bearings at high temperatures above 120 degrees; the scale of large bearings changes greatly; therefore; to achieve dimensional stability and disposal; otherwise; the fundamental additional dynamic load of bearings for over-scale stability; sometimes lower than bearings The fundamental extra dynamic load recorded in the scale table.
