Regarding the clearance issue of the compressor shaft

It must be a mistake! It should be somewhere between 0.2 millimeters and 0.35 millimeters
I really made a mistake; thanks for the reminder.
A gap of 0.2-0.35 is sufficient for operation; there is likely some measurement error in your data. If the bearing is equipped with a temperature probe, monitoring its temperature will suffice.
A clearance of between one-thousandth and one-thousandth five of the shaft diameter is perfectly fine!
