Anonymous Unregistered A	some time ago i sent out 3 sets of coated bearings -1/+1 and std size to a customer. he figured out which ones he needed and sent the others back. not thinking much about it at the time i put them on the shelf and there they sat for a couple of months. little did i think to look at them and make sure they were clean and not abused. fast forward to an occasion where i needed a -1 set of bearings. the fingerprints destroyed not only the Calico coating, but the lead/indium layer just crumbled apart too. they weren't even good enough for mock up bearings and went in the trash pronto. bearings could sit in oil forever, but fingerprints left on them will take their toll for sure.

I've found things wrong with bearings by feeling them that being "sterile" with them I'd have never found. Agreed you can't put something on a bearing and sit in a window sill to bake. Finger oil, lemon drops, alligator tears, chewing tobacco spit, BBQ sauce and so on. But outside of gold and titanium that goes for all metal. I think the spirit of the question was whether bearings should be handled or not during assembly and the answer is, yes you should. Hole in the sheet treatment of an engine isn't healthy.

Anonymous Unregistered A	i'm not totally sure of what the intent of the original post was. i just wanted to share my experience. as far as touching bearings goes, i touch every one of them i install in an engine as i put assembly lube on them. that's not quite the same as leaving fingerprints on them though, especially if it's for an undetermined amount of time.

I really think the old fingers, and nails are some of the best diagnostic tools we have. Since we're not making medicine and we don't use optical comparators and microscopes to look at everything, the fingers are great! I still after checking a hone finish with a profilometer drag my nails over it, and I'm as accurate as the meter
