hello sir,
i am into non standard bearing manufacturing,to get the cost of the bearing down i have designed a plastic retainer which hold the balls at equidistant also i have desined a capping for it so that the grease filled in is retained without any dust moving in the groove .i did the suceessful welding of it (derlin).but the machines manufacturers say that the cost of horn designed for me is to be beared by me i am ready for it but they say they cannot exactly tell me for how many welding times will this horn be intact which is making it difficult for me to deceide the costing of final product.i would love to show u the picture of the component if possible. bearing dimenision is weld area is just ( 12.5 - 7.5 )that is a thin rim u can say of just about 2mm in width

Hello,
Unfortunately there really is no way to tell in advance how long a horn will last. The main problem is you don't know how much amplitude will be needed to weld your component - more amplitude may give you a better quality weld but will certainly shorten the horn life.
But even if you knew the amplitude and could calculate the stresses exactly (and finite element analysis will get pretty close to this) fatigue fracture is still a rather random process. At best you'd get only a rough indication of how long the horn might last.
So I think the only real option is to make one and test it. Sorry, I know that's not the answer you wanted!
Regards
Chris
