Do you all know how to determine the distance between the two bearings on a fan shaft?
Thread Content
As the title suggests, how is the spacing between bearing housings determined? Are there any standards and references?
There are corresponding positions on the shaft for installing bearings; once the bearings are installed, the spacing is determined.
Do you want to measure the bearing spacing, or know if the bearings are in place?
There should be steps on the shaft; it can’t be completely smooth.
Agreed, how to disassemble, how to assemble. Don’t miss any items.
The manufacturer’s design has defects; it fails to take into account the direction and magnitude of the shaft’s thermal expansion, and positioning pins are not installed between the bearing housing and the base plate.
Based on the size and weight of the impeller, the stress on the shaft is calculated to determine the shaft’s diameter and the spacing between the bearings
Considering the thermal expansion of the shaft, there should be positioning of the bearing seat. Then reinstall it normally

The distance between the two support bearings is measured using the same measuring tool
