Given the diameter of the main shaft, how can one calculate the clearance of the main bearing shell and that of the larger bearing shell?
Actual size of the spindle + Actual size of the spindle X 0.2%. It refers to the actual size of the main shaft bearing shell, which is generally 0.02–0.04 threads larger
So if the spindle diameter is 280, what should the spindle clearance be?
0.15 percent to 0.2 percent
The clearance of ordinary bearing shells is between 1.5 and 2 percent of the shaft diameter. It’s best to stay within this range
This is your actual experience value; the exact figure is in the technical documentation.
The clearance of the bearing shells is between 1.5 and 2 per thousand of the shaft diameter
