The inner ring and shaft coordination

With the inner ring and the shaft, with no interference, no clearance of the state as the target (Line to Line). With the outer ring and the outer shell is movably matched with the hole.
Used in the same inner diameter of the casing in parallel with the double row spherical roller bearing case, outside diameter tolerance is F6, so as to be movable fit.

The clearance and preload bearings
Install bearings, applying pre load appropriate to give, as the axial clearance, the regulations are as follows.
Double direction angular contact thrust ball bearing--C7 clearance
