Beck-Arnly is a sourse of many OEM parts,they were also known as "World Parts" ...they were good quality and much cheaper than dealer cost,for the same parts..mostly for forigen vehicles though..
I sold National,Bower-BCA,Timken,Chicago-Rawhide,SKF,Mquay-Norriss and L&S bearings at various stores and dont recall any of those having failures really...but that was 15+ years ago too,back when quality was not sacrificed to match the price of cheaper bearings from no-name brands too...I used to see "country of origin" stamped in ink on the boxes,even back then most bearings were imported from Istanbul,Tiwan,Spain,and various other third world countries..
Timken was about the only one USA made back then...who knows where they make them today...lately its a crap shoot getting "good" parts,even long time trusted brands have cheapened up a lot and might not be the greatest...
Here you "might" get Timken bearings at some stores like Auto-Zone and Advanced Auto,usually they have to order them in though,since most people opt for the cheapest parts rather than the "best"...more than once my friend has called auto zone for wheel bearings and got three different brands,to do two races and cones--he didn't care as long as they fit,and were new...his customer wouldn't know any different either...
