How to Repair Broken Outer Ring of Giant Bearing? - Naaa it's bullshit - see pinned comment.

Just to ensure the customer will come back with the same issue in a couple months time...

@usr6874038614: I have all the tables and specifications of ball bearings from the manufacturers, along with aerospace requirements - from NASA and the like... THAT is changing the internal and external diameter of the bearing - so it's probably going to be a LOOSE fit or a NO GO fit with the housing and shaft - I do precision hand lapping of the shafts and housings..... The Cellulose Flux welding rods - they are a deep penetration arc welding rod.... They are not HIGH ALLOY, high strength and high hardness welds.... You can't heat treat them either, and they dilute the alloying elements out of the surrounding metal, into the weld pool.... So as the ball rolls, it hits like a mud puddle of steel, from very hard, to a little soft, soft and very soft - at the center of the weld, and in reverse heading out of it... That metal will flow from under the point contact where the ball runs over it - and that will indent into a groove and probably start shedding steel flakes and the ball race will develop "pot holes" on the welded areas... This is OK for a "This is the best we can do, with what we have", emergency type repair - and it's either do that or die... and then nurse it home... But these cunts are always rebuilding buckets of shit anyway... So fuck them. Don't buy any of their rejuvinated crap.

@usr6874038614: BUT the reason why I chose this image for a starter picture, is to show off the welding discontinuities along the joint...... Both on the inner and outer races.... Look closely on the BIG iMAGE - they are a dead give away that the bearing has been broken and rewelded.
