For months now I have maintained there is a big difference in the quality of the new rear bearings verses the original ones. Today I had time to compare an original FAG (Germany)and a new SKF (Italy) bearing shells. MY conclusion is what I suspected, the new ones are NOT the same. I took pictures and measurements to document what I saw. I hope the pictures let you see the difference. Guess which one is the original German one!

What's funny is once the bearing is in our car, we might let it go for 20+ years. Heat, cold, humidity, whatever.

What's funny is once the bearing is in our car, we might let it go for 20+ years. Heat, cold, humidity, whatever. because its not sitting static and the lube moves around.. remember earth vibrates at a constant? and the bearing dont roll on the shelf but they do vibrate.. and yes theres alot to do with what type of grease in the bearings, but bearings with no lube have a short shelf life! because no grease film between the balls and races...the stuff gets deep hahahah the microscopic film of grease is what the bearings ride on not the race (IMG:style_emoticons/default/smile.gif) |
