What is the maximum tolerance and minimum tolerance of the shaft and the standard bearing when the pump shaft is in alignment with the standard bearings?
With the shaft and the bearing is over with, is slightly larger than the shaft bearing, is in 0.001~0.002, so in the installation process of the bearing is installed, can never beat the way, so that the precision of the bearing damage.
This should be based on specific circumstances, different loads with different coordination, you have to check the bearing handbook to be, as a designer, tool is essential, bearing manual electronic version you can download a look, certainly a great harvest.
First of all, despise a Kazakhstan upstairs, the shaft and bearings are interference fit, rather than transition coordination. For the pump shaft, the tolerance zone shall be N5, and the specific tolerance shall be determined according to the diameter of the pump shaft by checking tolerances
