NACHI 7307C bearing

35x80x21

Specifically, I am looking to purchase six 30x62x15mm P4 grade 60* angular contact ball bearings (as manufactured by Barden, Nachi, SKF, NTN, NSK, Fafnir, etc), and eBay has a seller (raspartsales) who stocks these for $89 a piece, as opposed to $170-$450 a piece from the more reputable bearing suppliers I work with.
