We have already mentioned in front of the how to choose according to the basic dynamic load rating of bearing, at high temperatures using rolling bearing, bearing hardness drop, lower than at room temperature using fatigue life.
So, the basic dynamic load rating should estimate accordingly.
According to the correction.
Ct = ft · C type: Ct: according to the using temperature correction of basic dynamic load rating (
N)
, (
kgf）
Ft: temperature coefficient.
125 degrees, the coefficient is 1;
150 degrees, the coefficient is 1;
175 degrees, coefficient of 0.
95;
200 degrees, coefficient of 0.
90;
250 degrees, coefficient of 0.
75).
C: the basic dynamic load rating (
N)
, (
kgf）
Note that when using the bearing under the high temperature over 120 degrees, large bearing dimension change is big, so, want to undertake size stabilization treatment.
By the way, the size bearing of stabilizing treatment were related to the basic dynamic load rating, sometimes written in below table bearing size of the basic dynamic load rating.
