山东十一运夺金By liquid nitrogen or dry ice compared with cold press-fit assembly with mechanical press-fit method is more effective, then the standard freezing temperature of -40ºC~-70ºC, freezing time is generally 1 hour or more, according to the specific needs of parts of the wall thick and with tolerance.

Shrinkage of the bearing can be calculated according to the following companies:

△D=D×α×△T

△D:OD Diameter shrinkage

D:OD Bearing outer diameter

α:Linear expansion coefficient(1/105K)

△T:Temperature difference
