National Throw out bearing

[Flivver250]

I bought the Luk clutch but heard the horror stories about the throw out bearing so I got a National instead. 200 miles later the national bearing is chattering like the POS it is. Attached is a pix of the Luk bearing, which is so far out of round as to be a joke It has an eccentric orbit and should never have been packaged and sold. They must not have a QA/QC department, but I think National is just as bad. Does anyone make a good throw out bearing?

I did the same. Got the National, but it was more out of center than your Luk. Well like yours, mine is making a hell of a racket. I do not know of a quality TOB, but my luk did not look nearly as shitty as the National I put in...

I'm going to go to my local parts store and see what they have available, probably Chinese knock offs. Doubt I could do worse. Spinning the Luks in my hand is a real joke. It is so far out of round as to be laughable. The National looked okay, but it obviously was not.
