Ball & roller bearings have different kinds of problems than half-shell bearings. The cheap ones have one less ball or roller (in the same cage space) than the good ones. That reduces their life expectancy by more than 50% because of the geometry involved. The ball or roller surfaces crumble prematurely. With main & rod bearings it's more a matter of the material used and the skill of the assembler in setting up the clearances. ----- Original Message ----- From: Bob Bundy To: [email protected] Sent: Saturday, August 02, 2008 3:08 PM Subject: Dana Clevite vs. Federal Mogul Sealed Power rod bearings?
I ordered Clevite rod bearings from Napa. what I got was a box of sealed power Federal Mogul bearings with a "Napa Number" sticker over the part number that is the Clevite part number. Should I be concerned about this? They say made in Mexico, where as the box of Clevite main bearings say made in Japan. My previous experience with wheel bearings made in Mexico was not good. Timken wheel bearings of the same part number some made in Japan some in Australia but the ones made in Mexico always died an early death on the 323 as did any bearings that come from China.
