ah lol
i can only buy chain links from the web becouse nobody selse them in the netherlands 
I killed 2 bearings both in a week time and i'm not even doing crazy stuff with it and i'm oiling them.
I never saw t-swivels are they different then normal chain links?
normal ballbearing chain links(dazzle chux) has a breakable bearings that wears out by time
T-Swivel (example) doesn't have a bearing.. but a rounded "T" metal covered by a "U" (the metal itself is thick)

most of the T-swivel has a long chain.. this is the easiest way(and a closeup example)

U-swivel, in otherhand, is rare.. I bought my T-swivel in a bookstore's sports section lol. it cost here $ 3.25 USD converted from peso (PHP), so cheap, that I bought 3 of them ^^
