When idler pulley bearings fail!!!

Hey guys just like to let ya know new parts fail too!! I purchased the tweakit single turbo air pump removal idler pulley in the group buy. I put it on sunday and drove maybe 70 miles seeing the entire rpm range including redline. it failed 1/3 mile from my house conveniently. Im sure its not a defect in the part by anymeans a very well put together product

but i believe i got a bad bearing with it.

The bearing is McMaster Carr # 2349K471 for $18.16

possible ALT----honda #96150-60020-10 $7.xx average ebay 2x $3.95 + $8.75ship (this is a lawnmower bearing)

i checked he specs on it and it is well within spec at any rpm range with the stock main pulley it comes out close to 15,3xx rpm at 8K redline. The specs for the bearing are:

Maximum rpm
19,800

Maximum rpm Range
15,001 to 30,000

So its obvious there is NO DESIGN FLAW just a manufactur defect from the bearing company

havent heard back from chadwick yet on this but at least we know where to get the replacment bearing. as per install instructions reference

Well heres the carnage:
