1. Bearing heating temperature should be well controlled, high temperature bearings may be damaged, the temperature is too low the amount of expansion may make the ferrule insufficient, resulting in no significant eff ect. The amount of thermal expansion of the inner diameter of the inner ring of a heating temperature of 80 to 100 ℃ obtained, this amount having bearings usually over the amount of interference has been very adequate.precision bearings
2. Reach the required heating temperature is necessary as soon as possible to the bearing mounting, in order to avoid bearing cooling and installation difficulties.
3. Bearing cooling and contraction in the width direction will be installed to apply some pressure to the shoulder of the inner ring clamping operation, and done with a very thin feeler bearing cooling simple detector, depends on whether in the inner ring between the end face and shaft shoulder appears a gap etc..deep groove ball bearing
In summary, when the bearing mounting in claim skilled movements, quick and accurate.
