The repaired spindle with the cheapo bearings hasn't seen any service yet.

The top Fimec bearing appeared to be a standard 6002.C3 (open, extra clearance). HSD said they use 6002.2RSL.C3 which also is a common standard bearing. Realise that these are small diameter, low load bearings, and thus I don't feel the need to go for expensive bearings there. (They are also easy to replace).
