Where are thrust bearings generally installed on a pump?
This is related to the direction of the axial force on the pump shaft; if the axial force points toward the non-driving end, then the thrust bearing is installed at the driving end. The same is true in reverse. There are also exceptions.
Which pump? The cantilever pump is located near the motor side, while the pump with supports at both ends is installed on the side far from the motor
The cantilever pump is on the motor side, while the pumps with support at both ends are on the non-driving side
Cantilever pumps are installed at the drive end, while double-supported pumps are installed at the non-drive end
Since it’s a thrust bearing, the side that experiences greater axial force should be where the shaft is mounted; it depends on the forces acting on it
For single-stage cantilever centrifugal pumps, taking the stress conditions into account, the bearing on the side of the impeller in the bearing housing is generally designed as a cylindrical roller bearing, which primarily bears the radial forces on the rotor while allowing for some axial expansion of the rotor. Angular contact ball bearings, used in sets at the coupling end, mainly bear the axial forces and simultaneously position the rotor.
Under normal circumstances, cantilever pumps are installed on the drive side, while end-supported pumps are installed on the non-drive side
