e60 A/C clutch bearing went out and I made the mistake of replacing it with a low quality Chinese made bearing because it was the only replacement I could find.

Not surprisingly 3 months in, it started making noise.
I searched high and low for a German or Japanese bearing of this size. Had to settle on an FKG UK Air Conditioning Compressor Clutch Bearing 35mm x 52mm x 12mm (ahem, also made in China.)

Hopeful that this one will fare better than the Santech.
Any advice is welcome.
BTW the E34 "Ol' Red" with the rebuilt engine is at 250,000 miles and counting. Our E60 550i is at 205,000 miles and counting.
