**4. Discussion**

The journal and bearing combinations resulting into high clearances are not recommended as the load carrying capacity will be greatly reduced. Also, the ovality needs to be within range as it also has a direct impact (an increase in ovality leads to a decrease in performance). The measurements of OD, ID, surface roughness and ovality prove that the specified dimensions of the design are mostly maintained during manufacturing except in one or two cases. However, the user or application engineer needs to ensure that these geometric parameters are maintained during running condition of the bearing, which is a challenging task.
