    I am having difficult in calculating the pressure a bearing would experience, if it is placed inside a aluminum block of 42mm diameter. I know some pressure will be experienced by the bearing along the outer ring surface area as the aluminum block is placed at 20C temperature at first and then into a freezer with -85C. Thickness of the block and bearing is 12mm. Bearing Material is Silicon Nitride (Si3N4) and contraction of bearing can be neglected for the calculations.

    Please help me, i dont even know where to start!! I have calculated the change in area the aluminum block would have due to temperature change and it is about 0.995 mm2... HELP :(

    Sorry just a correction.

    Change in area of the hole is around 7.38 mm2.

    Thanks.
