Bearing Puller Facilitates Removal and Replacement of Bearing Assemblies 
The problem: 
To design a tool to remove ball bearing assemblies, 
which carry the rotor, from turbine type flowmeters. 
These bearings are usually semiconcealed and diffi-
cult to remove and replace. Returning the flowmeters 
to the manufacturer for bearing removal and replace-
ment resulted in several weeks loss of use.
The solution: 
A bearing puller which matches the bearing config-
uration to facilitate removal of bearing assemblies 
from the support members. 
How it's done: 
The head of the slotted screw is inserted in the 
inner race of the bearing to be removed. The wedge
