I can also confirm that both bearings I received are NSK printed. I've heard that other people who have ordered Timkins in the past have seen NTN and other manufacturers, so Timkin uses other sources for their stocks. I think Timkins is basically a reseller but in this case NSK is a good brand. Timken 510050 is the correct bearing for a 2001 Accord V6 *Update: It's 12th December 2019, the bearings are still working, I drive this car 5 days a week. No problems so far, it's been 2 years now
