Size of delamination of babbit in bearings

I want to compare the different criteria to accept or
reject the size of delamination zones of babbit in
bearings. Any help to find different specifications
will be apreciated.

I had never heard of the term babbit before another one for my downunder dictionary. The Australian Standard 2824-1985 Ultrasonic evaluation of Metal Bearing bonds has both evaluation and classifications of quality. Evaluation dtails the plotting of the poorly bonded areas. Classification has 5 classifications of quality based on both the edge zones and total bearing surface.

I hope this is of some use to you, I have a copy of the relevant pages in a works procedure if you require them for reference.

Re: Process for Bonding of babbit in bearings???
This is fairlu easy process. Using a straight beam probe. The calibration block is important.

Build a calibration block of similiar thicknesses as the component to be examined. Drill a 3/8 inch FBH to the interface of the babbit and the base material.

Establsiha thickness calibration. Determine the back wall single and observe the interface signal. Phase reversal is a good method to detect the calibration reflector.

Scan the componet to be examined. What for the interface signal.

We used this process in the US Navy.

: Make sure a quality flaw detector is available for the task. One with good resolution and RF display.

mances of portable X-Ray sets. Despite having managed to halve the weight of similar portable X-Ray generators available on the market (while continuing to provide the same power output), the SITEX CPSERIES generators feature a shutter, a laser pointer, a beryllium window, an aluminum filter and two integrated diaphragms (customized sizes are available upon request). Without compromising the robustness and reliability for which ICM products are renowned, the small size and light weight of the SITEX CPSERIES will radically change the way that you perform your RT inspections. And you will see a positive impact in terms of both quality and return on investment (ROI).
