Because of this, the parts integration of the thrust bearings will change the performance
and can cause a breakdown. When disassembling and re-assembling, the process
needs to be conducted with much care.
The thrust bearings (38-1, 38-2) consist of high precision class etc. of the front-to-front
angular contact bearings. The outer-ring is
隙間
so that these bearings receive only
the thrust load.
