SPINDLE BEARING REPLACING - ARROW 750 EKK

[Chivo]

Hi
The spindle from my Arrow2 EKK 5000RPM, failed. One washer springs broke and damaged a sensor. I pulled down the spindle and now I'm trying to refurnish the spindle.
Does any one have experince changing the angular contact bearings from the spindle. The spindle is AIR-OIL lubricated.
The original 3 bearings set from FIVES are over $ 2000
I have found NSK 7014CTR bearings with out the holes and grove for AIR-OIL lubrication, very cheap $320 duplex, I will buy 2 pairs; I was planning to send to some enginery company that modifie bearings, to add the grove and holes, also to make them a 3 set.
I'm going to share the pictures of my work.
PS: sorry for the bad english.
Any comment is welcome.
